While the malibu is still it shakes a lot seems like it wants to turn off. I put in Neutrol and the shaking is less, what can this be?

Is the check engine light on ?
Usually when the engine is shaking you have a miss where one or more cylinders are not firing or not producing power.

High idle on caddy cts o4 p2176 code

Can't help much on a cure but that code translate into this:
Throttle Actuator Ctrl Sys-Idle Pos Not Learned
Another lousy problem related to electronics. You might ask a chain auto parts store to reset this code (most scanners have that function) to see if it returns.

How do I ajust idiling on 97 malibu

There is no idle adjustment to be made on your car. The throtle position sensor takes care of it. The voltage at the tps at idle should be around 1 volt. if it's out of range check wireing if wireing checks out replace tps and idle should be correct.

My 02 malibu is idleing too hight how do i fix the problem. brian

Check your idle air control valve(IAC), it should be along your throttle body. Try disconnecting the wire harness to the IAC and see if there is a difference to the engines idle. If there is no change it may be dirty with carbon build up and seized, it needs to be cleaned with throttle body cleaner or it may need to be replaced. Good luck and hope this helps. After cleaning or replacing the IAC you need to reset the base line for it's idle, Turn the ignition to the run position for 30 sec and then turn the key to the off position for 10 sec then start the ending and let idle for 1 min then go for a test drive. Good luck and hope this helps.
