View Full Version : Misfiring...

well i recently had my motor rebuilt and its been running great but the Check engine light is now blinking, i immediately took it to AZ and it threw codes for misfire on all 4 cylinders...
i changed out the plugs yet ithe light is still blinking...any information? im not driving the car until i can get this figured out...im going to do the basics (cap/rotor/wires) and see where it goes from there...
the o2 sensor is unplugged but i dont think this would cause misfiring?
could timing be off? could the belt jumped a tooth? idk any help is greatly appreciated...

im not driving the car until i can get this figured out...is that because its misfiring or because your license is revoked?
Either way, good call , lawl

did it have any other codes to go along with it.
02 wont cause misfiring. to me it seems like timing has gone off. but like you said try doing the basic/cheap stuff first. and see what happens.

I would think the timing would be the cheapest, since you really don't have to spend any money, unless you check ignition timing too where a gun is involved...

by timing you mean taking off valve cover , setting the motor to TDC (what mark is it on the crank?) and checking the cams?

yup, crank pulley white mark on the lower timing cover mark and the cam sprockets both point up with the exhaust 3 o clock mark pointing to the intake 9 o clock mark.

my accord was missfiring, it just turned out to be the sparkplug wires, did you get a chance to change yours out yet?

i'm pretty sure he would have said if there were anymore codes when he mentioned this, not being an ass about it

just have to make sure. i see people post up asking about 1 code but will have a few others they leave out.
Benefit
05-07-2008, 01:30 PM
yes , there was a code for the o2 sensor and 7 codes for misfire...
i just changed the oil since it has been 500 miles on the new motor , took it high rpm past vtec around ~7k and the light is not blinking anymore....still going to change wires cap, rotor and check timing

No Mo Hondas has asked you more than once what were the exact codes. Yet you post up what you have. Appearently, you have no desire to get it fixed the correct way, yet you want an immediate, yet simple fix. All you have to do is post up ALL 7 CODES and win a prize!!! Seriously, every code has something to do with each other, especially if there's a camshaft correlation code. Plese post the codes.

there is only 4 codes for misfire...when i go to AZ again ill be sure to write them down...its a random/rapid misfire...
it started misfiring about ~400 miles into the break in period...the wires were the ****tiest wires i had ever seen , they wouldnt even clip on the plugs...the rotor screw was not even on...it was chilling at the top of the distributor and i saw corrosion on the cap so i thought surely that would fix it...
i took it for a drive this morning and the CEL was not blinking but the motor was not fully warmed up...so maybe a valve adjustment?
oh the light does not blink ALL the time , it will blink like 4-5 times every 10 min

no i havent but wouldnt timing be good if it was not throwing codes for 400 miles?

It sound like internals or somethign is seriously wrong.

i dont think u need a valve adjustment..u'd hear the engine ticking, not misfiring..
ur problem sounds like ignition or timing

i dont even notice it in driving , only way i can tell is from the CEL

That what it means when the check engine light is flashing. You already did the most obvious troubleshooting. It honestly sound like a piston ring or something. Don't quote me but that just my 2 cents could be wrong.
What is your setup?????
Benefit
06-03-2008, 02:47 PM
motor has new crank , rods , bearings , piston rings , headgasket , oil pump and all the gaskets/seals...
only thing internally i can think of is the valves not adjusted properly causing a messed up AF/R, which the o2 sensor isnt already fukking up...its a brand new bosch 200$ o2 sensor...just dont know the wiring...and being colorblind doesnt help
i guess ill compression/leak test?
gunna seafoam it today , see if it helps any...

What is your setup?????CEL can mean MULTIPLE things not just one particular problem. A Piston ring isnt going to set a CEL. A piston ring collapse will produce smoke out the tail pipe.

This is true. and lets not overlook the fact it ran perfect for 400 miles , and the misfire is not like the engine stumbling or anything.
I was about to say check you seals and vc gasket. Had that problem y-day. But very quick fix. But good luck finding your problem bro

You are right muiltiple of things. To determine whether a rings is collapse or not isnt smoke out the tail pipe either.

Yes it could. I am not the most technical person. I wouldnt make up nothing either.Everything I said is from experience.
Just comp test then work from there.

copied from a member who posted in my thread on H-T
are there any other codes? when does the code come on? during vtec? idle? normal driving?
per Helms, possible causes:
Fuel pump insufficient fuel pressure, amount of flow
fuel line clogging, blockage, leakage
fuel filter clogging
fuel pressure regulator stuck open
distributor malfunction
ignition coil wire open/leakage
ignition control module malfunction
valves carbon deposit
compression low
IAC vavle malfunction
Fast idle thermo valve malfunction
fuel does not meet owners manual spec, lack of fuel
VTEC system malfunction
test procedures and more info on page 11-78 of the integra manual

also a misfire on all 4 cylinders would be fuel related i guess...i also have a walbro 255 on the stock fpr/rail/injectors...

my car was misfiring, it was just a coil...
and it sounded BAD facking As$ while it did!!!

yea it doesnt make any sounds...
update-- i just put in a bottle of STP octane booster , and filled up...drove it and the light is not blinking (for now , i hope that did it..)
about to seafoam in a little bit...

06-03-2008, 05:39 PM
you dont need to sea foam of if its just been rebuilt.

you still haven't told me the set up. Is it aftermarket??? Did you raise or lower the compression????
Benefit

type-r pistons with new rings...
bottom end was rebuilt , seafoaming through brake booster would clean the head.
blackshine007
06-03-2008, 09:58 PM
^^ It actually cleans the top of the piston. It don't do much for cleaning the head if you're refering to the intake and exhaust ports. If you pull the intake and exhaust manifolds off and use pressurized air, you'll break off the carbon deposits that's lingering within each side. Just make sure that the valve that you're blowing out is closed.

well i seafoamed it , the idle even went down to 700 from 1000...and i havent seen the CEL blinking since.

06-04-2008, 09:14 PM
my guess would have to be in the gas. how long did the car sit before being rebuilt?
other than that if the valve adjustment is just a little too tight, there wont be any ticking, just misfires. anyways it sounds like you have it licked so good luck.

06-05-2008, 01:20 AM
yea...i really need to put in that o2 sensor, light comes and goes when it wants to...until i go WOT then it just dissapears for 20-30 min lol
can anyone help me wire it in?...its a brand new bosch o2 sensor...when i was pulling the motor it ripped out the male/female plug from both ends...now i dont know where they go especially since the bosch sensor has different wire colors...
blackshine007
06-05-2008, 07:53 AM
Why don't you just fix it the right way by taking it to someone who knows what they are doing vs. playing supertech and ultimately accomplishing nothing while the light stays on? Without fixing the problem, It's gonna take at least 40 key cycles before the light goes out. Everytime it flashes, that means yet another code popped up or the same code has come back up. OBDII isa totally different animal than OBDI.

06-05-2008, 09:00 PM
the O2 sensor should have instructions on which wire goes to which. just put bullet connectors on there so you can connect/disconnect them. after you are done correctly wiring the sensor, clear the ECU by either removing the negative terminal, or the 7.5A fuse in the under-hood fuse box named "back-up". voila, done.

06-09-2008, 04:12 PM
theres 2 blacks a green and a white on the bosch sensor...does anyone have a helms or knows how to wire it up?? too many combinations for me to connect/disconnect over and over again and its not in the most easy to get to place either

well...ive tried about 3 combinations so far and reset the ecu before i crank it over and light comes back...HELP!

ok first off, check out this thread..... http://honda-tech.com/zerothread/1901557
second, give us the codes that its throwing.
Last, if you changed all the wires, cap, rotor, plugs, and its still doing it, go to the local auto store and pick up a timing gun. This tool will help determine where your timing is at. Seems to me, that you may have jumped a tooth, lining up the marks on the crank isn't always accurate.
Benefit
06-09-2008, 05:33 PM
well i kept trying different combinations , and IT WORKED!, the CEL is not on anymore , the only light i have now is the ABS which is because i didnt use the ring on the new axles...car is almost 100% , just need A/C belt :) thanks everyone for the help in this thread. i guess the misfire WAS because of o2 sensor , i have a walbro 255 so im guessing too much fuel = misfire? anyways...i hope it never blinks again...about to change my oil and its only been 200 miles :)

what are you trying to say? the light did not blink this time when it went it went away completely , it just stayed on so i thought maybe it just came loose and it was an o2 sensor code...
if it was just a single misfire the light would come on, not blink?
1SOL2NV
06-10-2008, 01:41 AM
if it was just 1 .... it shouldnt blink ... but all 4 i think it will . to remind you to check the engine if it wont crank ... dont hold me to that tho .

06-10-2008, 10:20 PM
code is a p0132 , high voltage to the primary o2 sensor...i guess one of the wires are crossed
