stalling 1990 lumina

[tigerhawk1]

Hey guys I'm borrowing a friends Chilton Manual for my 1990 Chevy Lumina 2.5L and I was wondering is their any easy way of telling if my ICM is bad? Also once I get the codes I'll make sure to post them so that if anyone has a similiar problem to mine in the future my information will be of some help.

Take it off and have it tested at Autozone. (They do it for free,)

It does have a quick-connect fitting, and you can buy the tool somewhat cheap. You can do it without the special tool, but it requires some dinking around. the tool is cheap so I'd just go buy it. Also, to prevent spraying when you disconnect the filter, first pull the fuel pump relay and crank the engine over until it won't fire. Since the fuel pump isn't getting any power, the fuel pressure will diminish. You can also do this by unhooking the wires that are connected to the pump, but It's a lot easier to pull the relay.

"The 2.8L and 3.1L v6 motors ....... and a new VITON (not rubber) O-ring from the dealer that seals the former distributor shaft hole. That plug has a seal that cracks and leaks oil all down the side of the motor."


when you go to the trouble of replacing the "o" ring spend another $.98 and put a distributer gasket on the "oil pump drive shaft"
