Well I guess I fried it. I put it back in, cleared the codes and went for a drive and now it's throwing:
335 (O) EGR feedback signal is/was out of range
and
558 (O) EGR vacuum regulator solenoid/circuit failure
So, now I know the EGR/VRS is toast but what started the EGR problem ? Could the differential switch be bad? Where is it and can it be tested ?
Oh yeah, did you know that if you don't put the speedo cable back under the MAF that it will eat itself ?
