DO YOU HAVE A HELMS MANUAL. if not get one they really help alot .just take your time looks scaryer that it really is. or see if there is another zr1 er in your area that might help ya out .
Thanks, I have done this on L98s so should be OK, are these a ZR-1 only part or can I find new one easy? I have factory ser. manuals and a Haynes which seems easier to muddle thru.

you got the big fat red manual with the electric and engine suplement.they can really bug ya on the order of things in the book. but once you learn that system its way more detailed than the other. ck the map sensor vac line .it at the back of the motor up against the wall

Cool Re: Stalling at stop

Cleaning IAC worked for me , I use starting eyther to clean parts like this drys fast , sprays hard and won't destroy stuff!! Take toothbrush or
Q-tip to clean cavity on throttle body, mine was caked with goo.

I had this exact problem with my 90, turned out to be the speed sensor on the drivers side of the trans. I'm not saying this is your issue but it was for me...worth a look.
