Crossfire injection
Hello all,
I purchased an 82 in April and am having a series of problems with the crossfire injection. A new computer and air sensor were installed. Following the advice of Twin Turbo in response to a posting by my friend 78 Vette SA, the throttle bodies and plates were adjusted. The hot idling has improved. Thanks guys. But the cold idle is still a problem. My mechanic who did the work says the idle control motors are not working. They were working before, but both have stopped. The computer is working OK according to him. Any suggestions?
Thanks

The idle air motors are easy to check, ground the ALDL and turn the key to the on position, they should start cycling in and out.
What are the symptoms? What is the cold idle rpm at? Are you in a cold climate? Fuel puddling is pretty common on crossfires, turn the heater on to allow coolant to pass through the manifold water jacket and heat the plenum
