I love my car, and would be heartbroken to have to replace her, but im sitting on the line of whether it's time or not. 2001 grand prix GT 3.8L V6. Been having problems after problems and tired of taking it to expensive mechanics. Hopefully you guys can help.
Problem:
-Stalls in low RPM
-RPM fluctuates (100% of the time when i first turn it on, randomly after driving and randomly during park)
-might be unrelated, but the car sometimes violently kicks into gears. this has been happening for a while and only getting worse. Transmissions dying I'd assume.
Questions:
How can I fix the stalling problem? I will likely buy any needed parts from a scrapyard, as i know the transmission will die before new parts go bad again.
and
What can I do to prolong the life of my poor transmission?
Other info:
100+k miles, no check engine lights, fuel gauge sensor is broken, been using the car's gas usage sensor to judge when i need gas, just got a new catalytic converter, 2000 miles since oil change. problem occurs with cold and warm engine.
any help is Very much appreciated
