Hello,
I have a 2004 Grand Prix, NA with about 160K miles and it's been pretty reliable but it's always had a few quirks but it seems to becoming a bit more problematic.
Since I've owned the car (2014 it had 80k miles) it required some coaxing with the gas to start up, turning the key without pumping the gas a little would often result in a stall. This has never seemed to get worse but is just part of the state of things
New Problems:
- When I am gently accelerating I get an oscillation in the rpms in the mid range. I've tried replacing my MAP sensor which saw some improvement from when it was really bad but it seems to return regularly. While my warranty at Autozone stands, I'm getting rather tired of swapping them out.
- When I close the hood I can hear an electrical crackle like arcing. I haven't seen any electrical weirdness from the other systems (unless the rpm one is related) but it's concerning
- Today after opening the hood to check oil before going to work, I heard the crackle on close and my high blower went out. (Haven't had time to check the fuse)
Mainly I'm trying to figure out where I should start tracing that kind of electrical issue as I imagine it's a bad ground or short that jumps along the hood. (This is all observable when the car is off by the way)
