1992 Chevy silverado will crank but run at a low idle..when I mash the gas it shuts off


There are a variety of problems that could cause that, but if you mash the accelerator and it dies, you may want to put a fuel pressure gauge on the fuel rail to measure your fuel pressure. Assuming you have the V8 350 in it, that engine can require upwards of 30psi at the rail, and even a few pounds less can cause it to stall. You may have a dying fuel pump or clogged filter. That's where I would start, hopefully this helps!

1983 s10 blazer low rough idle and trys to die when starting have to give it a little gas and put it into drive real quick then when slowing down keep foot on gas pedal as i also slow down with break pedal


Could be several things, a vac leak, dirty throttle body, or faulty idle air control valve.
The computer controls idle speed by how much air enters the throttle body thru the valve.
Usually a vac leak would speed up the engine unless it is causing the rough idle.

92 ford ranger when first started excessively high idle


Could be a vac leak, or a faulty idle air control valve on the throttle body.
The computer controls idle speed by regulating the amount of air entering the intake.

How do I advance my engine ilde speed it seems to slow when at a red light its about to cut off .


i would suggest cleaning the throttle body before adjusting anything, disconnect the air cleaner assembly from the engine and have somebody hold the gas pedal to the floor with the engine off and use some carb cleaner and spray it on a rag and clean all the black stuff out of the throttle body that is just beyond the throttle plate that opened when your helper pushed down the gas pedal,that should cure your low idle problem,hope this helps

Service engine soon is on and the truck idles low when cranked.


Take the vehicle to an autoparts store and have them use a scan tool to retrieve the fault code(s) stored in the computer. Most stores offer this service at no charge. The codes will help identify the problem. Sounds like a faulty Idle Air Control (IAC) valve to me, but the codes will narrow the reason down. Hope this helped and best wishes.

1997 mazda protege engine cranks and idles but when you mash the gas pedal rpms will not come up and motor sounds like it is choking down.it has a new mass airflow sensor,pcm,fuel pump.what do i need to do


Have you checked the exhaust for a restriction, it may be a clogged catylictic convertor. Any muffler shop can assist you in checking for a restricted exhaust, they most likely will not charge for it.
