p0512 bad grounds check them all ,, (worst case get a 8 or 4 awg wire attach it to the long bolt of the starter to the ground of the battery ..
p0511 iac valve ( idle air control valve issue) this is random check it first and there is a way to check it or do what I did .. remove the intake clean the crap out of the throttle body and maf sensor and try a Lil sea foam my issue cleared up after some driving .. and make sure your using 93 octane ..may not b related but it makes a huge difference in performance ..
I hope this helps every scenario is different

i would doubt that it is a cali spec because the production date is 07/97 and i live in canada and car was bought in canada. I also looked under and saw 2 o2 sensors in the y pipe and 1 right after the cat.. but the cat looked like it had a spot for a 02 sensor in it but there was a bolt there.. reason being is prolly that cat was made for cali and non cali spec and of course the cat is aftermarket bosal

ok thanks for posting the diagram it makes sense now.. the code is there because i have a little exhaust leak right before the rear O2 sensor at the flange where the cat meets the mid pipe. ill get that sorted out and a new knock sensor and my CEL should go off.. Fingers crossed!
