Ls2 402 idle problem
Ls2 402 idle problem I have a 402 with a Texas giant cam, Fast 90, NW 90tb and I am running a speed density tune. I have been messing with this setup for about six months and I have yet to get it to idle right. Mike at Rapid Motorsports has played with the tune three times now and I am still surging and stalling when I come to a stop. I can't find a vaccume leak or an exhaust leak and the car gets worse with cold weather. If the temp is around 70 the car is fairly drivable but when it drops below 50 outside the car dies everytime I stop. I would greatly appreciate some help. The rest of my setup is in my sig. Thanks
