CEL still on... need advice.
Hey guys,
P0306... cylinder 6 misfire. This is what I have done so far: New Plugs New Wires New Coilpack Full Seafoam Treatment Techron Fuel Injector Treatment Compression check on Cylinder 6 = 140 = good Brand new fuel injector in Cylinder 6 Last night while driving after I put the fuel injector in truck ran fine all day. Then while in In'N'Out drive thru, CEL flashes, then goes solid. P0306. Reset the code and socked my steering wheel a few times. Is there anything else I can try? Is my computer bad or something? I've pretty much cleaned out my bank account trying to get this CEL to go away. Any help would be greatly appreciated. |
torch the truck and get the insurance money lol

x2. Drive it to Mexico, park it in town with the keys in the ignition and the window down then go have a few drinks.
Can anyone shine some light? rwenzig? earl? beard? shane from boring oregon? |
is the misfire still present?
|
but make sure to take your glass off first

How is the coolant? Maybe you have a small headgasket or intake manifold gasket leak.

I hope it's not a head gasket leak, all that **** was supposed to be brand new and reconditioned when I got this dang engine from www.karking.com blah. |
Do the Mexico thing and pay off the truck with the insurance money. Or pray that you get T boned but you end up uninjured. Then buy a new Civic and leave it stock.
Oh and I won't ever deal with KarKing. No thanks. |
i had a misfire from my egr being bad. i wouldnt think thats your problem though. this is weird
|
do you have an egr?

Google says p0306 is caused by:
* Faulty spark plug or wire - NEW * Faulty coil (pack) - NEW * Faulty oxygen sensor(s) - Replaced 6 months ago * Faulty fuel injector - NEW * Burned exhaust valve - ? * Faulty catalytic converter(s) - ? * Running out of fuel - .... * Poor compression - Compression is good * Defective computer - ? |

ECM?
Found this on another forum: whitedevilTA Senior Member Join Date: Dec 2005 Location: Northern CT Posts: 251 Car: 1986 Trans am Engine: Minirammed 355, TF heads, XR276 cam Transmission: T5 manual Axle/Gears: 95 10 bolt, 4.10 Classifieds Rating: (2) My ECM went bad once on my 86. Car would run perfect and the engine light would be off but as soon as the light came on(and it came on completely randomly) the car would go berserk and idle crappy, hesitate, backfire, you name it. But it only did it once in a while, and the light would sudenly go off and it would run perfect again. You should get a code too telling you the ECM is bad......I did when mine went bad. Sounds just like my issue. |
IDK. Like you mentioned PCM, burned valve, which could be possible. Also weak or broken valve spring. I am out of ideas at this point you have replaced almost everything related to fuel and ignition. You could do a cylinder leak down test.

when i had my misfire issue everytime someone else had one it seemed like their peoblem was my problem too. well after replace everything i could thing of i still had the problem, then a friends granfather said pull the vacume hose off the egr and drive home and see if thats the the problem, he said if u pull the line and it runns perfect then thats it and you need to replace it. well i thought that was crazy. after a month of the problem i gave it a shot. and there ya go that was it.
so to check the egr pull that vacume line off and drive it. it wont clear up instantly but after a few miles if thats the problem you'll know after about 2 or 3 miles. it doesnt hurt anything so dont worry. i doubt that would be it but im sure your willing to give it a shot. driver side manifold is where its located. |
