vibration at low rpm when at a stop. vibration increases when ac is on.

I'm getting a P0128 CODE on my Trailblazer. It is caused by a defective temperature sensor or thermostat. Where are these items located?

a whining noise comes from under the hood when the key is turned to acc. sounds to me like it is coming from the throttle body assembly

My car RPM moves but car can't pick up some time goes till 60
what is the problem

looking to buy this car but it has a leak not sure price to dfix

I have ticking under hood, bogged down acceleration, strong exhaust fumes and some smoke at times from tailpipe. Oil pressure is good and ticking speeds up with acceleration. Please help!!! :(

It's not the battery. Could it be the shifter assembly or a shift lock control solenoid? I can only move the key forward once I need to move it forward again to have the key come out of the ignition. GM has me confused about what parts I need. Prices vary depending on what they think I need. I know that it has to do with the shifter because I took it apart and the part on the shifter does not come up the whole way for the piece on the shifter to release the key in the ignition. Do I need to replace the solenoid or the whole shifter?

no problems up to now

I have had this issue checked 3 times so far and again the check engine light came back on after having the issue "fixed" by the dealership. They said it was a faulty part at first. What the heck is going on here. I just purchased the truck 3 weeks ago?
