Question about 1991 Buick Regal
I have a 1991 buick regal with a 3.8. last night it died. it was very smooth just died. then it wouldnt start for 10 mins throwing the temp light. ever since it has run extremely rough. had no horespower very sluggish. and i get a burning smell comming from the car. after a lot or research I spent 300 dollars today and replaced the Cat thinking it was plugged. well that didnt fix the issue. Im not loosing oil or coolant. obd picks up a mis fire. but wats the burning smell aswell. i need help bad. i just put 300 into this for nothin...
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 # .

You might have to check you coolant to see if exhaust is leaking into it. I had the same problem and melted my water pump. just from a bad header gasket.
