Cylinder 3 Misfire

[gtshaw]

I picked up this code two months ago, and I cannot get it to go away. I changed the I bought a new motorcraft coil, and 7 new boots, but I cant seem to get rid of it. What else can be causing this code.

Have you had the code cleared with a code reader?? This IS a Gen II, correct?

 

[gtshaw]

Yes, I have my own code reader. I erase it, and it comes back.

..and you DID change the plug? Is the plug wet when you pull it?

 

[Sapperfire]

what code are you getting?

 

[gtshaw]

I'm getting P303. My plugs aren't wet. They are dry. New Autolites. Just to verify the firing order is this correct?

4 8
3 7
2 6
1 2

Not unless you bought coils for a V7...

Can we assume the 2 under the 6 is supposed to be a 5?

Depends on where you are showing "front" of car.... # 1 is the front plug on pass side. # 5 driver's front. 1-2-3-4 Pass side 5-6-7-8 Drivers side

That's what I figured. Can there be anything else setting off the P303?

 

[budpytko]

Not according to my book.... My advise. Take everything off #3 and put it elsewhere and see if the code changes..... obviously....take what is on where ever you and put it on # 3 and see if the code switches cylinders. Then you'll know for sure it's either the plug or coil/boot.

My latest misfire adventure was dueot a bad fuel injector.
