added cam idle issues 350 chevrolet

I have a 1989 V1500 Jimmy, has a 5.7 non vortec head engine. added the comp cams 12-304-4 cam using my tbi set up. The only issue is when idleing the idle drops down and causes a stall or if I pull up to a light to stop it will stall, The engine light comes on showing egr issue, but egr is brand new……

  1. If you insist on using the TBI setup you need to swap out the computer chip with an aftermarket of you will continue to have this issue no matter what you do. Contact Summit Racing or Jegs tech center for one that matches your cam specs.
