OK, this is odd.

Try this file please.

that one is actually MUCH worse.
Surge now is very violent - it will jerk the truck forward when in gear... its very rhythmic, but very pronounced.

Throttle is still dead. I watched it on our scan tool and throttle angle changes but tps1 voltage stays flat at .69V in most cases. TPS 2 stays around 4.8V

rarely it will let the engine rev, and when it does the tps voltage will change as it should, then it will go back to acting a fool and wont pull.
Again, hitting the gas when its acting up will either cause the car to stall or the RPMs will drop to 3-400 rpm

well... that helped with the surge... but the check gauges light is still on and there is absolutely no throttle response.

I am flummoxed.... where do we go from here?

whoops, just saw that last one...

one sec

cool, let me know.

We found an old file from another customer with the same issue (same calid) and saw what we did to fix his, thats what is in the _001 file I posted last

well now... that one didnt fix it, but it sure was fun to drive!

I got excited when I started it because the surge was gone and it was idling about where it should have.... for about 30 seconds.

Then the check gauges light came on and the idle jumped back up to over 1500rpm.

The really fun part tho was when you would hit the gas... it would do nothing when you gave it throttle - but then about 5 seconds after you let OFF the gas it would jump to around 1500 and take off!!
so, hit the gas to slow down and let off to make her go!

Ummm....not good.

Looks like we have some issues with this cal, we'll need a bit of time to look into it.

Thanks
