My '92 Buick Regal Custom has an issue that is somewhat similar to previous questions. I have a bit more detail than others have had so I am hoping that I get a better response. The motor is a 3.8L. Any answers will help out tremendously.
The issue is an intermittent stalling of the engine. The vehicle will run fine for weeks on end then suddenly it will leave me stranded. The pattern seems to be as mostly in town driving, foot off of the accelerator, brake depressed. The car does not shake or shudder, no strange sounds, just silence. Power steering and power brakes are obviously useless. Hazards and dash lights work. Heater blower works. Sometimes the vehicle starts right back up and runs fine. Sometimes it needs to sit for 15-20 minutes. Sometimes it starts but stalls within a time frame of 200 ft or within 5 minutes of restart.
I have also had this happen after I have shut the car off. Getting back into the car it may take 20 minutes to start. One thing I have observed a couple times is the cd player will reset to track 1 or turn off completely without being able to be turned on for weeks after-wards, then suddenly it will come on by itself as I am driving down the road.
The codes I have had in the past were 17 and 23. 23 is MAT sensor-signal voltage is low or high OR TPS error OR Mixture control solenoid-open or short circuit problems. This code is not currently present. 17 is a hard code, present after reset. It is listed as the following RPM signal problem OR Camshaft sensor- circuit problem OR ECM computer circuit problem- Pull up resistor (Saturn).
The camshaft sensor was replaced in Nov. The ECM, I'm not sure how to take that. Does this mean it is only for Saturn or both GM and Satun but only the Saturn with the pull up resistor? Also ALL of the choices seem to me to be very vague. The ECM still has power flowing to it when the car stalls, couldn't all of these thing be attributed to the fact the engine isn't running?
I am wondering if a TPS and EGR combination could be causing the stalling. Also this vehicle has been wrecked. There were no problems until then. The gas mileage has decreased tremendously from 28 mpg highway to about 18. I have also noticed that idle is 500 RPM and will fluctuate slightly up and down 100 Rpm. I have read on forums and such of these issues being from TPS to coil packs to ECM. Does anything I have here rule out anything? Thank you in advance for your help.
