hey guys have an issue i was hoping someone could help me out with. the car idles fine and with moderate pulls nothing happens, but when brought to redline the car will either stall when i come to a stop or idle down under 1k and almost stall for about 15 secs then it will level out again. however once this has happened, until the car is turned off if you even touch the gas it will bog back down for 15secs or so. car is running a haltech platinum sport 1000 ecu, gsc 272 cams, gt 3076 turbo, can list more mods if its needed to help.

 

Not sure what you mean by pulling but I think I'm having a similar issue. Car starts fine idles at 1000 rpm. First gear engages ok. Then is I have to stop, when I depress the clutch and brake the engine drops below 500 rpm and stalls. AC is not on.

Haven't changed anything that would account for this problem.

 

By pull I mean redlining the car. I can drive it normal as the car will be fine. If I redline any gear the car will either stall when I come to a stop or bog down well below 1000rpms when I come to a stop. It will continue until the car is shut off and started again

 

I had the same problem 2 months ago, I ended up finding my self looking in the engine bay and saw that one of my vacuum lines had rotted out a few holes and cracks. I replaced them with some new ones and believe it or not it solved my stalling problem and the occasionally under rev problems the car stared running a lot smoother no stalling after pulls and no under revs. I'm not sure if it will work for u guys but I would give it a shot.

 

Thanks for reply, ill go trace all the vacuum lines and make sure it isn't something small and simple like that.
