I've seen a bad ETA throw Odd codes (shorting wires do wonders for DTC's).. Cut the wiring insulation open and have a look..if it's bad it's bad so I wouldn't be to concerned wiggling it about.


As for code checking, I've never seen a 90.....follow Jim's site, build a code reader and go through it step by step..his site is an utter WEALTH of information!!!!
