misfire on all six cylinders on a 2003 accord v6

[stephanie]

what the hell is wrong with it....what would make that happen. me and my friend are going to try and fix it. but i think it is going to have to be taken to a shop.......any suggestions? please!!!!!!

last weekend we figured out the passenger side headlight was out, and you have to remove the whole friggin battery to change it.

Spark plug wires. (coil pack) if it has one... Plugs.. Dizzy

[stephanie]

thanks...she did go get the code pulled earlier.

just trying to see where to go next with it.

[Black4DrEK]

^ I would go with Wires, plugs, ect...

Start small then work your way up!!

[stephanie]

its all six cylinders though...thats the fucked up part.

[.blank cd]

I would start with a trip to Honda

[Black4DrEK]

Does it have any Oil leak in the Head? can you see oil all over the Valve cover gasket?

[BTEC]

did u have anything done b4 it started acting up?

[Black4DrEK]

I would start with a trip to Honda

^ and spend a ASS LOAD of money!!

[terrytowe22]

crankshaft sensor

throwing parts at it due to lack of diagnostic skills or unqualified shop could cost more. kinda like a gamble either way unless a friend with skills works on it.

[Barefoot]

does it miss when it hot or cold or both

[Black4DrEK]

take plugs out and see if they are Covered with OIL...

[BTEC]

crankshaft sensor
explain your theory if u dnt mind. and how would one go about testing to see if thats what the prob is.

throwing parts at it due to lack of diagnostic skills or unqualified shop could cost more. kinda like a gamble either way unless a friend with skills works on it.not really all that true. my truck was at the dealership for 3 day last week. its also going back for 3 days this week. thats all they are doing is throwing parts at it.

[terrytowe22]

well on my buddy jetta vr6 it would run like crap it would cut out acting as if it was misfireing so we changed the plugs nothing happen did a whole tune up still did it so we change the crankshaft sensor in it ran perfect



but it was just a seggestion
do you know for sure that it is misfiring>?

explain your theory if u dnt mind. and how would one go about testing to see if thats what the prob is.

[Black4DrEK]

^ yes she said they had the codes ran allready

[terrytowe22]

also to test it take it out in see if the little circle in the middle of the sensor, check to see if the magnet is not gone.

[BTEC]

not really all that true. my truck was at the dealership for 3 day last week. its also going back for 3 days this week. thats all they are doing is throwing parts at it.
WTF?!! And ur paying for it?

[stephanie]

thanks. i will talk with her tomorrow. maybey find out more info. i need to go to bed early i feel like crap! but im willing to drop about anything to help her.
and she needs some daylight to look at the car

[stephanie]

i really appreciate the help too!!!!

[terrytowe22]

^ yes she said they had the codes ran allready

[Black4DrEK]

[.blank cd]

i already gave my advice

[im_hung]

03 v6 accords have an issue with the egr port getting clogged.
i would check the egr port...

but that will not make it misfire!!!

tune up, ecm,something in the fuel etc

[Tech5]

i was about to say the same thing.:no: :no: :no: :no: :no:

Not the problem:":":":":"

i retract my statement. (i would check/clean the egr port anyway :D)

update your pcm software. should cost about $85 at your local Honda dealership

If he has no egr codes don't waste the time , its not a issue at this time.

Do you just say random shit?

take it to a shop. It sounds like an easy fix with the proper computer.

[Black4DrEK]

It could easy be the Coil pack/ plugs!!

This thread is full of fail. lol

The only things that could , under normal circumstances, cause a random multimple cylinder mis-fire Code P0300 is Crankshaft position sensor, Camshaft position sensor, or ignition control module. Possibly the coil pack but only if its for all six cylinders. Not plugs/wires or anything that is dedicated to a single cylinder. The code means mis-fires on multiple cylinders not intermittent mis-fires on a single cylinder.

[ej6kidd]

I HAD BOUGHT A MAZDA 6 WITH THE SAME CODE AND ALL IT NEEDED WAS THE SPARK PLUGS AND COIL.

[stephanie]

seems like it was some sort of computer malfunction. the mechanic pulled the code and she told me it spit out a bunch of codes. he test drove the car and said it "ran like a scalded ape"
and thanks again everyone!

[Black4DrEK]

^ good to know

Does it have any Oil leak in the Head? can you see oil all over the Valve cover gasket?

oil on the valve cover gasket can mean a number of things..........:thinking:



i didnt read the whole thread, but something this new(2003) and all cyl are misfiring...prob some sensor or somethin


and yes a trip to the dealer will probably clear things up pretty quickly.

Hey, I kind of have to same problem on my h22. Me and my dad changed the plugs and got a new distributor cap. He has a coil up at a shop that we are going to try next. Then wires, then rotor. When we fix it, ill tell you what it was and maybe it will help.

[Z0_o6]

first off, 03 Accord V6 has coil packs. if it is showing a misfire code for all 6 cylinders, it is not likely that all 6 plugs/coils crapped out simultaneously. Does the car run rough? Did she have the drive belt replaced recently? If so was it a Honda drive belt?

[Black4DrEK]

:thinking: I think she got it fixed, it was a ecu malfuntion or something along those lines!!
