Ok, did some more work on the car...
Cleared all the codes and none came back. Ran a can of seafoam through the pcv and found exhaust leaks in the driver side y pipe, and the seals in the junction. Ran a compression check and 1 was a little lower than the rest, but within norm. It idled better cold this morning (stable at 1k RPM), but now stalls and dies when braking
Any ideas?
Oh yeah, after clearing the codes, the seat belt light is flashing.
