High idle shifts hard but idle will go back down but shifts hard

You'd probably have to take it in to get it diagnosed, but I'm going to guess that it's the electronic throttle body.
The throttle body and throttle position sensor are in the same unit and if one goes bad, you have to replaced the whole thing.

This will cause high idle, stalling, hard shifts and irratic throttle.

Cle stalls when going to reverse to forward trailblazer 07 throttle body

I would check the idle control solenoid first. it is mounted near the throttle body or on it. When engine rpm drops it pushes the throttle open to keep it running. It also keeps idle up when switching on the
a/c and can be used as a quick check for the solenoid.

2004 trailblazer when i turn heat on truck vibrates and turns off. was told it could be a sensor but dont no where they are or which one.

Time to clean throttle body, a dirty throttle body will cause low idle and stalling. Make sure to disconnect the battery during the cleaning process, this will reset the PCM (computer) so it can relearn to the cleaned throttle body.

I have a 2002 Chevy Trailblazer. Just replaced

If you unhooked battery it will need to relearn its idle position, should help if you clean throttle blade edge and body of carbon so proper amount of idle air can enter engine.

Can a bad AC Compressor cause the engine to stall during idle on a 2003 Ford Taurus?

It could if the front bearing is locking up, this causes the belt to stop which in turn could cause the concern.

Idles up and down when my 2003 trailblazer is in nuetral

Here is the common problem and fix.

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
