My 1993 olds cutlass supreme idles fine until you step on the gas or when your going down the road at higher speeds than idle it has a hesitation what's the problem?


A flat spot on acceleration could be low fuel pressure or a faulty throttle position sensor. Could also be a vac leak such as a faulty EGR valve.
Is the check engine light on ?

YOU SHOULD HAVE VACUUM AT IDLE TO MAP SENSOR.WIDE OPEN THROTTLE VACUUM WILL DROP. SO YOU NEED CHECK AND REPLACE ALL VACUUM LINES ON INTAKE MANIFOLD.THATS WHERE YOUR MAP SENSOR GETS IT VACUUM FROM.

My 1993 cutlas supreme stalls randomly while idling or driving , but restart right away


You will need to change the crank position sensor first and see if it corrects the problem. It is located behind the engine near the firewall. It's a bit tricky to get to it, you would need to rotate the engine forward then look under the exhaust manifold and under the cylinder closest to the drivers side. Use a 10 mm deep socket to loosen bolt. After replacement and it is still stalling then you will need to replace the ECM (vehicle computer). If it turns out to be the computer, go to your local junkyard to get an inexpensive replacement Click on the link below to view the CPS, it is around $22
