Its funny Chris, I mentioned to you the first time I pulled the 880's out the rubber grommet (not o-ring)was lopsided going into the fuel rail. Well after I installed the stockers I put back in the 880'sto see if reseating them properly fixed the solution. This morning I decided to put the stockers back in again to positively make sure it was the 880's giving me a problem. I noticed one of the injectors (the same one as before) still didn't seat right and that damn gommet going into the fuel rail was lopsided. I ordered new injectors Friday so I am just gonna wait for those to come in before I put the 880's back into the car. I think that rubber grommet is stretched a tad and is sitting properly when I tighten down the fuel rail. The only other thing I can think of causing this is just some random issue my car in general is having with upgraded injectors.

 

Same issues. Car starts fine when hot but if its warm its giving me a problem. Cold start are okay but stumble a tad when it first fires up. It almost seems as if the cold start crank is too short.

 

keep us updated after you put the new injectors in

 

Eric looks like you finally figured out your problem I guess there was nothing wrong with your tune just you tech skills...lol

 

No nothing, just some knock on spool up.
