Vette w/ new problem
Ive got an 86' Vette and I just installed BoschIII fuel injectors from Jon @ fuel injector connection and the car runs much better but I have a new problem but not a real critical one , When I first start the car cold it will start right up and run @ 1000 rpm's for about 2 minutes then it will start to surge low then high and low and high till it warms up(approx 5mins)then will settle right down and idle @ 700 rpms. before the install I had a slight surge at startup but now is it worse. could something like a temperature sensor or something else be causing the surge. Like I said before ,once it's warm , it settles right down. any suggestions would be helpful Thanx

i have an 87, that pretty much does the same thing...
on cold start, runs about 1000, fluctuates between 700-800 for a couple min, then settles at 700.
warn start, runs about 900 for a couple seconds, then right to 700
I think your normal.
