SOURCE: Mazda astina bg series 1992

the idle air motor in the throttle body is probably not working right it lets more air in the intake when its cold and is supposed to shut off when it warms up if its not shuttin off then it is probably not closing

SOURCE: 1997 chev runs but seems like not getting enough fuel.

Marshall, Before going to the expense of replacing the fuel pump, I would recomend a fuel pressure check. If you do not have the equipment, take it to your favorite mechanic and ask them to check. The pumps and strainers run between $180 to $400 depending if reconditioned, new and brand.
Let me know.
Regards,

I am having a similar problem and my mechanic thinks it's a fuel regulator. Part was ordered and it's being replaced this week. We'll see. Unrelated, I'm/we're having a heck of a time finding an oil pan...mine is very blistered....but it is 17 years old.

SOURCE: wont keep idle, car stalls out

I had this same problem on my 2005 monte carlo, took mechanic a while to figure out it was the idle air control valve. They also replace the idle air control motor.

93 5,8l. Ford F150xlt throttle cuts out while driving, realese petal and works again.? New f filter and plugs wires


I had a very similar problem. Mine was caused by a weak in tank fuel pump. As long as I wasn't asking for too much fuel, it ran fine, but the moment I put my foot into, it would cough and sputter and try to die. But once I pulled my foot off the accelerator It would either cut off completely or idle and run fine, until I again would try to make it over the hill into Hillsboro. Hope this has helped you

When my car warms up it will not stay started it will die unless i keep my foot on the gas petal to prevent it from dying


Change the sir-filter and fuel-filter. Also clean out the air-filter box the filter sits in. If the problem persists, remove the air-intake duct that goes to the throttle body for obstructions. Also look at the air-horn and throttle-plate. Is there carbon in the air-horn and throttle-plate? If so, carefully clean the airhorn and throttle-plate with a clean, dust-free rag sprayed with automotive solvent.

If you still have the pronlem, you might consider the engine temperature-senser.

I have replaced my fuel pump, filter, throttle position sensor, and relay on my 1992 jimmy. it runs but everytime it hits idle speed it cuts off. what could that be


It should have an idle air control valve which lets air into the intake to control the idle speed. The valve could be faulty, or dirty, or the throttle body could be dirty. The computer opens and closes the valve to regulate idle speed.

Check the throttle body butterfly flap, its propably very dirty, holding off the flap at idle will cut it out. If its dirty, then get a can of carburrettor cleaning spray and clean the throttle body, that should do the trick. Hope that helps
