Lately my car has been giving me quite a bit of trouble and I wanted to see what you guys think. When I first start the car it will not idle and I have to keep it revved up, but I can't hold it at a steady rpm or else it will die, even while i've got it revved up. After about 5 minutes or so of this it will finally slowly start to idle on its own but then the air fuel guage starts to go lean and it wants to die until I rev it up then it will run fine for about 10 seconds then it will try to go lean and repeat itself over and over again. The engine is a 355 with ported LT4 heads and intake with a custom blower cam built by LS1 Speed. The car no longer has a blower on it and I'm running the stock injectors. PCMforless did the tuning. What should I do? Any suggestions?
Thanks, Randy

 

Anyone?
