co-worker has an 05 trailblazer.
Just started today, with a very bad miss hesitation at low (<800) rpms.
Have to give it gas just to keep from cutting off.
Goes away under throttle runs extreemly smooth.
No problems getting up to highway speed etc.

Any guesses?

Throttle Position sensor?
Crank PS?

what else?
 
05? I'd just take it to the dealer and have them fix it under warranty.
 
well it was at th dealer when I posted....

Just looking for alittle insight and a few educated guesses...

Turns out it was the cam position sensor.
Apparently there is a screen on the CPS and it was damaged (how?) and causing faulty readings

It's a chevy! They self destruct!:flipoff2: Actually I'd bet it hit the crank because it was improperly installed at the factory. You'd have to see it to know for sure. If it isn't off roaded or anything chevy should replace it irreguardless.
