I just looked on their site and seen what you mentioned. I thought I got my LTFT and O2 PIDs from the XGauge page I guess not.

I don't remember where I got them and I do not think O2 and LTFT are preprogrammed.

So 96 SL1 I put 2 bottles of chevron injector cleaner in the tank then went to the chevron station and filled up. I thought for sure it was the placebo affect but after about 20 miles of driving the car seemed to be clearing up. After 40 miles the car really cleared up. Iíd say the bucking and surging and spitting at idle was 80% gone and the timing at idle was now between -15 to -22 degrees. Still jumped around but the window was narrower now. After 90 miles the car was slowly going back to bucking and surging and the timing all over at idle again. Obviously itís probably not going to go away on the first tank. Iíll run chevron for the next 5k miles and take the plugs out and see what the piston tops look like and hopefully the injectors clear up.
