Question about 1991 Buick Regal

1 Answer

Hey. you responded to my question about the 91 regal acting sluggish the warmer it gets and the longer i drive it in one trip. ive pretty much knocked out the simple stuff. since i have owned it i have taken great care it. i used to work for goodyear. ive done water pump, alternator, belt, transmission fluid exchange and new trans filter. fuel filter, coolant flush, thermostat, rear struts oil change every 2 grand. and i threw a cold air intake on it for the hell of it. i think it could possibly be the intake air temp sensor because it adjusts the way the engine acts to the temp of in comming air. but im not sure. oh btw it has 115,153 ish miles

An air ambient temp sensor wouldn't have that kind of effect on the engine. I would lean more towards the CTS. Also I would check the vaccum line running into the MAP sensor as well. The mileage doesn't indicate a converter issue.

Do you have a check engine light on? If yes; try to get the code, have someone loan you a scan tool to access the codes. If you do not have a check engine light on it is not a ecm control issue, ie. (cam or crank sensors etc). Suspect the fuel pump. If you are certain it is working ok. Next is to check the coil pack and Ignition module. Look for spark at the plugs. Pull a plug wire and look / listen for spark to jump out the end to bear metal as you spin the engine trying to start it.

Get the fuel pressure checked after you change the fuel filter. The magnet on the came gear will most likley need to be replaced. The timing cover will need to come off to do this. While you are in there replace the chain, cam thrust spring and tensioner too. The cars with 3800's will usually shut off when the crank sensor gets hot after driving. Cooling it with a spray bottle of water will sometimes make them run. As for you case when it acts up spay it and see if it clears up. If so replace it. What are the engine codes? reply

Car problem with 91 buick regal


Replace the timming chain, gears, and magnet. With that cat getting that hot it has to be out of time. When the cam sensor picks up no signal, ecu can't control timming and reverts back to a preset,fixed base # .
