Re: 1989 Camaro Dies In Low Rpm's

sounds more like a bad fuel pump or clogged fuel filter to me.

Re: 1989 Camaro Dies In Low Rpm's

usually a bad filter or weak pump will show up at higher rpm or under heavier load as the car is using more fuel...another thing it could be is the iac motor...really need to get it scanned or jump out the aldl connector to get the codes...but i might be of more assistance if you got the codes..

Re: 1989 Camaro Dies In Low Rpm's

The computer controlled engines need a very good ground circuit too. One simple thing you can do is follow all the wiring from the TBI injectors and make sure none of the wires is rubbed bare. Also pull all connectors apart and look for corrosion or dirt....they need to be clean, tight and a little dielectric grease in them guards against moisture. Do the same for the wires connecting to the oxygen sensor and coolant temp sensor. One member stated his coolant sensor was leaking just enough coolant under pressure to force it up the wire harness to a connector and caused a short. Make sure the ground wires from the engine to body and body to battery are free of rust and corrosion as well. All the electrical connections are extremely important on these cars and can cause all kinds of trouble. If it still acts up after all that, then I would suggest clearing all the existing codes at the aldl connector and drive for a short time to get new codes stored. You will then have a good record of immediate codes to have read and determine the problem. It could be a faulty TBI injector, oxygen sensor, coolant temp sensor, etc.

Good Luck......

Re: 1989 Camaro Dies In Low Rpm's

also tap on the map sensor with the car running...see if theres any change in idle...if there is, change the map sensor...

sometimes you`re the windshield and sometimes you`re the bug...

Make sure both injectors are spraying fuel.

Re: 1989 Camaro Dies In Low Rpm's

hmmm, did I see this one before? Is it still live?

#1 cause of a flaky or irregular idle on an EFI car is a dirty or bad Idle Air Control motor.

Look for a 1" diameter by 1" long cylinder, 2 ears with screws screwing it to the throttle body somewhere, has an electrical connector.

Take it off, and clean it good with carb cleaner and a toothbrush. With luck, problem will go away and never come back. If it goes away for a while then comes back, get a new one. If it don't go away, keep looking.
