Idle position switch or sensor. I had 93 that would stall when i came to a stop. Cost me $43 but it was worth it. I don't know if this will fix it, but it sounds like it would.

Location of thermostatic switch 1993 Buick Regal 3.8 motor fan motors don't run


The fans are controlled by the ECM and it uses the ECT sensor for temperature sensing, so if the check engine light isn't on the sensor is not the problem. You need to have an active test run on the fan system to see what code is returned. Have you tried powering up the fans at the relay?

My 93 buick regal custom 3.8l has a bad ac pump and makes an aweful noise when running. The ac doesnt work and the 'clutch' on the pump spins freely, is this an easy fix or do i need a new ac pump?


you would need a new a/c pump, however you you didnt want to replace it and could live with out the a/c, a cheaper option is to replace the belt and bypass the a/c. Most auto parts store will sell you a belt of the correct dimensions if you tell them you wish to bypass the a/c. I've done this for many customers. It can be done on just about any motor.

Best of Luck.....

That fault indicates a problem in the electronic cooling fan circuit. More specificly the output driver in the onboard computer has detected a problem with the control circuit of the electronic fans. First inspect for correct operation of both radiator mounted fans.

sounds like you have a severe vacuum leak, causing a lean condition. The car runs for a short period because of the rich mixture the computer provides for cold start-up.

Buick Regal 3.8 dies while braking


Check to see if you have a lot of dirt in the throttle body. Clean the throttle blades out with brake cleaner or throttle body cleaner. You'll see alot of dirt come out. Keep spraying until it comes out fairly clear and wipe the throttle body out with a rag. If this doesn't do it, you may have a problem with the throttle position sensor (TPS). This sensor controls the idle after the car warms up and keeps it from dying when you brake or sit at idle.
