2002 C5 Running Badly
To keep things short, I got my rear main seal and housing replaced at the dealership last week and my car now seems to need to be jump started every morning and it also idles very unsteady (like at 5000 and then dips down, even shutoff on me once so far). I plan on taking it back to them on Monday but maybe you guys can be of some help. Please and thank you!
Update: I got a check engine light after running the car for a while and I had 2 misfires and a code saying I was running lean. I reset the codes and I will be running the car for an extended period of time tomorrow to try and get the codes to pop back up.

Welcome to the Forum but let the dealership handle the diagnosis if all the trouble you’re having now started after they worked on it…we can only GUESS here…we can’t give you an accurate diagnosis…did you mean 500 RPM not 5000 ??

I did mean 500, my bad. But will do, hopefully it’s a quick fix.
