Cold Start Surging

[BoDapper]

Hey guys-

Got an 87' K5 with a fresh 330hp TBI engine that is surging with cold starts. Hasn't been much of a problem with warmer weather, but as the temp is dropping in the mornings now it tends to surge hard enough to die.

It's got a new re-man TBI along with new IAC, TPS, O2, and water temp sensors. I've thrown the old TBI and sensors back on it to check the new stuff out- but had the same results.

Called the outfit that burned my chip for me- they claimed that it wasn't the chip- had to be something else.

The distributor is original, could it cause the injectors to surge with cold starts? Am I over looking anything? Any ideas or comments will be greatly appreciated.

Thanks,
Chas

Take your air cleaner off when you start it and check for icing on the throttle plates.

My tbi would ice up so bad when it was damp and cold (Maine) that it would eventually stall out and there would be pools of gas on top of the throttle plates. I solved the problem by reserecting the thermostatic air cleaner.

No icing problem, thanks for the idea though.....

Anyone think the distributor could cause the injectors to surge with cold starts?
