got the car back.... now im getting a loud pop out of the rear that i can feel in the seat of the car when i drive over dips and such in the road, my check engine light just came on again, and my exhuast fell off while i was driving it. the exhaust seems to have been removed and that they didnt tighten the bolt on the clamp good enough, i retightened it and havent had it happen again (about 4 full rotations of the nut!). im going to hit it with the obd2 here in a lil bit, but that pop is scary as **** and i'm very worried about what that can be, no vibrations in the rear on the highway, no out of the ordinary whining or anything, only happens on dips or places where the chasis is flexed. i drove it 200 miles this weekend, round trip to my cabin and back, and im pissed that evertime i get the car back something else is messed up! i'll post what the trouble code is later.
