Engine/Transmission (1998.5 - 2002) For Those Who Haven't,reset Your Apps.....

[kdunham]

I just got a PM on this subject(kind of) but I finally got around to doing the APPS reset procedure the proper way today and I gotta tell ya', if you have stumbling issues,power issues or anything you may believe is fuel related you should really do this. If you have done it properly and you still have problems,then skip this entirely. I was kind of hard headed and didn't believe that it would make this kind of difference. My APPS says a voltage of . 521v DC on it,according to the DVOM it was set at . 240 v DC. That's quite a difference and it showed when I got it set and drove it. I don't want to sound like a faith healer or a quack but whoever posted this fix knows what they're talking about,try it,you'll like it.

Could this issue have a lot to do with poor mileage as well?

I doubt it - the APPS only affects relative throttle position, not timing or fueling percentages - those are handled by ECM/PCM...
