today my friends took his gauge cluster out so he could scrape the orange off his needles. after he put it back in the truck runs like ****!! doesn't pull nearly as hard, just feels like it has no power.

i wouldn't think the gauge cluster would have anything to do with performance of the engine but maybe i'm wrong. any suggestions?

 

Was the key on when he removed the cluster? Maybe one of the ciruits in the cluster that gets an output from the PCM was disturbed...the speedo and tach get their signals from the PCM...I wonder if having one of those circuits momentarily open could have affected something...doesn't really make much sense, but it sounds like something happened.

 

at work ive driven a truck without a cluster and it felt fine, maybe something else happened to the truck.

 

Gimme a call, I got an extra cluster he can try.

 

thats nuts, sounds like something went bad with the electrical, the guages them self have nothign to do with the engine, they only read what its doing, not control it, why would he want to "scrape off the orange" anyways?

 

I have also unpluged the cluster with the key on, (didn't meen too) and everything was fine. Did he do ANYTHING else while the gauges where unpluged?

 

That makes no sense. Good luck getting that one figured out.

 

This has nothing to do with the guages but it kind of sounds like a timing problem. Just my thoughts from what you described. I as well have driven the truck without a cluster and it ran fine.

 

Paint the needles back orange quick!!!!!



Actually Idont know why it would be . Mine drove to the store and back fine with out the cluster and drove just fine after I put it back

 

No Kidding!!! That must be the problem...I mean..I have seen it happen before and if dont put them back to the exact color of orange...kiss your motor good bye!!!LOL
