1993 Pontiac Grand Prix LE review from North America
What things have gone wrong with the car?
2 issues:
Engine runs hot, but doesn't overheat.
Emission test failure 4 times in a row.
General comments?
Overall, it is a reliable car. Leaked oil until I changed oil ring on the oil shaft and put silicone on the cap. This is the most common spot for leaks on 3.1s.
Who knows how to get the temperature down? Why does it run rich? Is it ECM (computer) set up?. My temperature gauge is half the way (which is good for winter), but I am not sure I will like it like that during the summer. I do not lose coolant, which is a good sign. People say that my engine runs rich. Who has the same problem and how to handdle it?
Emission failure is due to the high cylinder tempereture. Passes everything except NO.
My previous car Lumina (which is the same drivetrain as Grand Prix) never overheated. I found out later that the thermostat was stuck open. Maybe I have to put it on Grand Prix?
