T00BiGT00FAST

I just made a mass air conversion on my sons 87 GT using a pro-m kit.The car seems to stall at lights.I talked to pro-m and their saying the computer hasnt reset but I heard it could be not having the fuel pump and speed control hooked to the new computer.Any thoughts!

Well the ecm has reset and adapted and learned by your first stop sign!

Then I guess I need to hook up the fuel pump and speed control to the new computer then if thats the case.Its really wierd the car runs great just doesnt hold an idle coming to a stop unless I rev it before I come to a stop.Thanks for your help!

speed control would be a really good idea, as the car will raise the idle once it goes past 3MPH, and keeps the car from stalling by actuating the IAC

Jegs-
Granatelli #467-81868801 -This kit is real nice kit and comes complete with all of the needed wiring and pins.the Pro-M kit you can get doesnt come with extra pins for you to hook up the speed control and fuel pump if needed to.thanks

Sweet. So all I'd need is that sensor, that wiring harness, and the computer?

where are you getting the pin connectors to plug into the computer. i know 2 wires are spliced and 2 are plugged in.
