Hello Jared,
I myself am an Aztek owner and had similar issues.. Your case seems like it might be something more simple and you might be looking past the basic so let me suggest the easy stuff 1st and then move on to the others

1st pull #5 plug check condition and also check Gap ... so many times its just the gap on the plug

2nd Check or jsut relace the wire make sure it is not burned and that proper connection is made.

You have Clean oil and its not leaking anywhere as you stated so I would rule out head gaskets after I checked the antifreeze condition if it is milky in color bad news its a head gasket not its fine...

next I would do a compression test on the cylinder with plug out of cylinder in ? hook up your gauge and have a buddy crank it over compare it to all other cylindfers and see if you are losing compression if you are then you have bad rings ofr valve seals. a slight fluxuation in volume is normal not all will read same but a major difference means trouble...

BTW injectors on the 3,4 liter gm are mechanical and very rarely ever fail if it was injectors you hear a loud ticking and a few light taps will free it up

unfortunately you are still in troubleshooting stage please send me a message if you need someone to think it through with you again best of luck...

This may sound dumb, but my aztek said the same exact thing and the problem was in the spark plug wire. The end that goes over the spark plug had a loose fitting inside, causing a bad spark relay. Try replacing that, or at least checking it our more.

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.

2001 pontiac aztec replaced spark plugs then fuel filter old filter was full of dirty gas car started right away then took it for test run tried raising rpm and bogged out then service engine light started...

We stopped guessing back in the 90's when car makers started using trouble codes. So should you. Blinking check engine light means you have a serious misfire. So doubtful that it's an electrical problem. Get the codes read and post them. That's the starting point. We stopped guessing back in the 90's when car makers started using trouble codes

I have a 2002 pontiac aztek and my service engine soon light is on. How do I turn it off?

Go to any autozone,oreilly, pep boys, Napa . Tell them your engine light is on and they have a code-puller that can turn it off, they will try to tell you they cant turn check engine light off without you fixing the problem or "buying the part from them, but most of those kids will anyway. If not go to a shop and pay way to much to have it turned off, or buy an inexpensive code puller (40.00 - up). you buy one I can explain how to use it buy email.

What causes the service engine soon light to come on

There are about a million reasons why the service engine light comes on. It could be a sensor gone bad, needing oil change, wrong fuel pressure, misfiring on a cylinder. So many things will cause it. You can go to Autozone and they will hook it to their computer for FREE and tell you what is wrong.

2002 Aztek Service engine light on & high beam indicator flashes

The high beam light flashing means you have a high beam burnt out. It flashes when you put it in gear because your high beams actually double as your daytime running lights, only on a lower power.
