Hopefully this got yer other problems fixxed up to. Don't forget to update your help thread if it worked for the next poor victim of the same symptoms.

so i deceided to recalibrate the apps.
i just tried this and it worked. i had played with my old apps that i replaced 2 years ago. it had a random revving problem. wich didnt work. then i came across this thread.
while i obviously didnt fix both. it did work for the new one.

my apps tested at .490 volts.

now .531 sticker said .534:rocking:

where the pics at .lol

You guys are confusing me,how do I know if the Apps needs reset or not,my truck runs good,but I have had a fairly massive drop in MPG,I'm getting about 15mpg now,and I used to get 21mpg.
I have not noticed anything wrong with my EGT's,they might be a little warmer than before,but not too bad.

You got nothin to lose by tryin it. It doesn't cost a dime, takes about 1/2 an hour and doesn't put any parts at risk as long as you follow the directions.

If you have any loss of power, loss of MPG, higher EGT's, dead pedal or many more symptoms it can be attributed to this. Over time this sensor just works it's way out of adjustment and needs to be reset.

This can also cause Surge Issues if your APPS is out of spec.

Just did mine; APPS states .525 and mine was at .417.
We'll see how it goes.

I would like to do this but just installed a DDt noise filter and I tapped the orange/blue wire on C1. Would this effect my innitial reading?

Nope

I notice a difference! Truck is definitely more solid! But wait...maybe that's because I filled up my tires a little more.....:choochoo:

But seriously....after I did it, the CEL came on. I drove it for about 5 min to the carwash, wasked the truck, and when I started it back up, the CEL did not come back on.
It does seem to shift a little better, and the unlock/lock problem (in another thread) did not happen last night. I'll see again tonight....
