Before you spend anymore have it hooked up to a real time engine analyser like a bdm pro, or a snapon scanner, take it for a drive and snapshoot scanner when the problem arises, could be a sensor like tps or an actuator, but will not register a code, just a flag

Where do you add refrigerant in my 2001 Pontiac Aztec

first find and fix the leak in the system or you will be wasting gas
gas is added via the suction line point at the compressor and is added until a set pressure is achieved in the system
really it works out to be cheaper to have an accredited ac specialist shop do the job

My 2001 Aztek started stuttering over 35mph. Thought that it was the injectors, so I added injector cleaner.Then added gas treatment. So, what do I check for next, in order of importance??

If higher mileage.. I would check spark plugs and ignition wires. You could be experiencing a misffire. Does the check engine light come on or flash when this shutter happens? If so, a misfre may be present.

Misfire on Cylinder 3 swapped plugs between 3 and 4 on Pontiak Aztek 2003. Misfire remained on cylinder 3. Swapped ignition coil 3 and 6 with ignition coil 1 and 4 misfire still on cylinder 3

Try a new plug wire on cyl 3 if that doesn't fix it you could have a bad valve or compression problem on cyl 3 Try doing a compression test also If it has injectors for each cylinder you could have a bad injector for cylinder number 3

Stalling at low speeds for a 2002 Pontiac Aztek

Does the battery light come on before the engine dies, or after ?
After is normal because the engine is not turning the alternator.
Is the check engine light on when the engine is running ?
Common causes for stalling are a dirty throttle body or faulty idle air control valve.

2002 Pontiac gran prix engine stall while stopping, then it will restart but runs really rough like its misfiring, but then whn givin any gas or shifted from park or neutral it dies again.

Please include engine and mileage to help with answers. There is a sensor in the tube connecting the air box to the throttle body. Map, mass air flow sensor. It is delicate and pricey. The auto parts has a aerosol can of cleaner for about 8$ designed to clean this part. Carefully remove it from the tube housing and spray it off with the cleaner. This cleaner will attack the plentum and tube melting it causing air leaks if you use it in the tube. On a 3800 If you have coolant leaks or seeping check the plenum it may need to be replaced if it has not already been. They have a new style that is reinforced. This should smooth out the idle and clear up stalling if it's dirty. Air leaks can also cause an unstable idle and stalling at stop signs. Anti freeze can turn corrosive and should be changed. I change mine about every 3 or 4 years. Make sure if your engine contains aluminum parts ( block or heads) that you use the correct antifreeze when refilling or adding to existing levels. Green or orange. Read the label to make shure the product is correct for your car.
