TPI 85 iroc......runs VERY crappy when cold, ?????

Seems like the cold start part of my fuel injection on my TPI iroc doesn't work. When I first start the car on a cool day, it almost dies and barely runs, then backfires through the intake a couple times as you take off. Then when it warms up to about 160ish, it runs perfectly fine and doesn't exhibit any of these problems. Whats going on here??? No engine codes either.

I think he meant Cold Start Injector.

However, I don't think the cold start injector is the problem because it only is on when you turn the key.

I'm sorry, but I don't know what the solution is to your problem.
