Ok, Ive just spent a few hours going though the car. First off, the god damn thing wont read codes with out moving the ECU connector. The pins are all good and tight on the connector. I think I have broken connections in the ECU or something. Because when I move the connector the LED light flickers on and off.
So after playing with it I finally got these codes and for some reason I cant retrieve any others or reset the ones I have. This is a passat ECU (i thought they were the same ECU's) and im getting the code info from a golf/jetta bentley since the passat bentley has no info on this.
1231 speed sensor
2142 Knock sensor #1
2144 Knock sensor #2
4431 idle stabilizer valve
and I have these that make no sense
2222
1221
4441
I know that the aftermarket chip will eliminate the need for the speed sensors, but I have had 2 GIAC's and both ran sh1tty and had no power. So Im trying to figure out if I have another problem.
My original problem is that the car had a fluctuating idle which is now gone after 20 cold starts. But now when stopping the car will just die. When I put the clutch in and let the revs drop to idle. If anyone has any ideas, please help. Im about to burn this f'kin thing, I swapped from CIS-E to eliminate any tuning problems, I guess that didnt happen
