Last weekend pulled the 9th injector cold start and fuel line and put in the Accel block off kit. Started it up today...cranked over first time and to my amazement NO typical puff of black smoke. My car has just turned 50,000 miles and for years had this annoying problem. All thought that it was the typical "valve seal" thing. I also noticed that when I increased the rpm while it was cold; no crackling in the exhaust sound or mini backfires(only happened when cold on start up). Very interesting that GM eliminated the cold start injector in 1989...coincidence??? makes me wonder...!!!!!!

The valve seals will be a puff of blue burnt oil. Black puffs are fuel.

When GM eliminated the cold start injector, they richened up the tune in the computer chip to compensate.

What is an MRP eprom? I know what an eprom is but haven't heard of MRP.

The 9nth injector can be removed, just need a chip burned to mantain cold start quick starts. I ran into this dilema when I installed a T-Ram on my 87, no boss for the cold start injector. Ed Wright burned my chip, no cold start issues.
