dropped off my little hot rod today for check engine light. Dealer said it keeps coding as a no4 misfire, after coil and injector swap, still has the issue. They asked me for permission to drop fuel tank, they are thinking water in fuel, when I asked if others where showing a misfire, they said no just number 4.
I just dont think water in fuel would only misfire one cyl??? Let me know, Help!!!

 

I wouldn't think that it would, I would guess the coil pack.

 

I would check the compression in that hole.

 

^^^^^^ yep, first thing.

 

Whats the recall?

 

No recall.

 

Sorry I didn't finish it. I was wondering about a service bulletine for this problem.

 

No TSB, just something we started seeing about a year or so ago.
