1995 Buick LeSabre 3.8 Liter Wont start unless I push down on gas pedal like it wants more gas, Why? Runs OK when running


Possibly a bad or dirty Idle Air Control motor. The engine computer controls the operation of this motor to control idle speed. A pintle on the motor extends and retracts, according to signal from the computer. The pintle controls an air passage below it to give or take away air during idle -when the throttle shaft is closed, no air will get into the engine through the throttle body except through the idle air passage . The IAC motor or valve is on the throttle body, with a 4 wire connector. Take it off and look for carbon or coking deposits around the valve's pintle, and in the air passage beneath it. With the idle valve off, plug the connector back on it, then watch the pintle as the key is turned to on. If there is no movement whatsoever, the motor is probably bad.

I have also heard that a bad coolant temperature sensor can cause such a hard start. If the computer does not know the engine is cold, it won't put enough gas into the cylinders for easy starts. The engine needs more gas to start and run when cold.

Motor starts fine runs for five minutes then dies starts back up back up fine but no throttle response after thatfine.


if there is electronic throttle then probably needs replacement, get second hand one , or otherwise can try to take it out and clean it, if there is an access to electronic part of it try it open carefully and clean contacts with some alcohol, sometimes it helps

Motor starts and idles ok but dosent respond to throttle.


It's possible your control "computer" had a glitch. If it happens again, or if you're just curious, have a diagnostics check. A simple check is free at many auto parts stores. I hope this is helpful.

CHECK THE IDLE AIR CONTROL MOTOR OR THE THROTTLE POSITION SENSOR. ANOTHER PROBLEM COULD BE THE MASS AIR FLOW SENSOR

1998 Durango will not idle


Check A.I.S./I.A.C. motor on throttle body. Known by both names, Automatic idle speed motor (AIS) Idle Air control (IAC) . Usually mounted on side of throttle body, with 2 or 3 torx screws and it's job is to adjust idle at all times as necessary, such as when AC on, turning, etc when extra load on engine, it will increase idle as needed to overcome the load and maintain proper idle speed. You can often remove the motor and clean pintle (pointed end that goes inside throttle body) with throttle body spray cleaner as well as spray inside the port (hole) that it comes out of. Sometimes this will cure the problem for quite a while, but if only for a short time, and it happens again, replace it.
