I'm pretty sure I have a low fuel pressure or some type of fuel surge issue... This is only when the car is cold, and only when I first pull out on the road.
Every morning upon startup everything seems fine. The motor cranks immediately and turns right on. No problem. I'll idle out of the driveway and immediately into first gear i'll notice it sounds a little odd, like there's no power there and it seems to hesitate; during this time the LC-1 wideband shows between 9-10! (When I had the GT it had an overheating issue, and everytime it got hot it went into limp mode and there was an extreme loss in power) That's the best way I know how to describe the symptom...
Anyhow, i'll stay out of the gas for a few seconds and slowly build up RPM then immediately I can almost feel it kick back in and all of the sudden it feels completely normal again... The wideband comes back to around 13-14.5 where it always is. The car will be fine basically for the rest of the day unless I let it sit for an extended period of time.
I cannot remember any specific mod that I did when this started, it has been doing it basically since I did the drivetrain swap. The car was well on its way to 500RWHP on the dyno but then started hesitating around 5800-6000 RPM. My tuner could not tell what the issue was and he de-tuned the car and it still made 430 with 15 degress until I figure this out...
It still has the stock pumps with the KB BAP. The only thing I can possibly think of might be the PPRV delete which I did myself... Would this be consistant with a crimped line possibly? Any ideas at all on this one?
Any help appreciated as always thanks guys! :beer:
