{: ) I presume that your a/c compressor is not seized in any degree, for you can hear squeaking noise from belt when a/c on. I suggest you check the throtlle body for carbon build-up. Clean it with carburetor cleaner and afterwards perform an idle reset. You may clean the air filter as well.

mcdevito75 here, That"s an expesive job approx. $500.00--------$800.00

Your injectors could be dirty, or bad, also plugs could be filed.

Hi Deettec

your problem seems very easy :) hope this one work with your envoy. Just buy AC DELCO carburetor tune-up conditioner.

How you use it: engine running , AC off please

1. detached the big black airflow hose which is attached in the mannifold of the engine block.

2. ask your friend to step on the gas pedal and set the rpm steady in 2000 rpm only.

3. then spray vigorously in 8 seconds the inside circle opening of mannifold while your friend steady step on gas pedal with steady 2000 RPM only.
