Ok, first race of the year this past weekend at IRP, and had a really strange problem all weekend
The car is a 83 Rabbit GTI, I just converted it from ITB to GP, the only change motor wise was the bottom end, made no other changes
Here is what it was doing, ran great before the weekend and in the paddock, good idle, etc, go out on the track, runs great for 3 or 4 laps, than just dies,acts like you hit a rev limiter,keep your foot in it will move but continue to die and lose speed, take your foot off the pedal and it just dies, wont restart, will fire but just dies after it goes to 2 to 3000 rpm
water temp was under 180, oil temp was normal. EGT 1350 to 1400
Toe the car in, and push it under the canopy wait 5 minutes more and the car starts and runs great, the idle some times jumps up 500 to 800 RPM's
This happened all weekend both days, we changed the following to no avail
Control Pressure Regulator
Coil
Wires, plugs
Oxy sensor
Pulled the fuel pump relay and ran a jumper
None of those worked?, anyone have anything similiar? or know a hint or fix?
thanks
