misfire on all six cylinders on a 2003 accord v6

**stephanie** · 04-21-2009, 08:25 PM

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** · 04-21-2009, 08:37 PM

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

just trying to see where to go next with it.

**Black4DrEK** · 04-21-2009, 08:42 PM

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

Start small then work your way up!!

**stephanie** · 04-21-2009, 08:43 PM

**.blank cd** · 04-21-2009, 08:44 PM

**Black4DrEK** · 04-21-2009, 08:45 PM

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

**BTEC** · 04-21-2009, 08:45 PM

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** · 04-21-2009, 08:50 PM

does it miss when it hot or cold or both

**Black4DrEK** · 04-21-2009, 08:50 PM

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

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** · 04-21-2009, 09:00 PM

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

^ yes she said they had the codes ran allready

**terrytowe22** · 04-21-2009, 09:02 PM

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.

Do you just say random shit?

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

**Black4DrEK** · 04-22-2009, 01:49 PM

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** · 04-22-2009, 06:10 PM

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

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** · 04-23-2009, 08:48 AM

^ good to know
