If it were me, I'd see if it runs better with the MAF disconnected and check for vacuum leaks. Make sure the air filter is new, or at least not too bad.

If it runs better with the MAF disconnected, it either wasn't replaced or is defective. Vacuum level can be tested or you can do a smoke test. There are many suspects for vacuum leaks, but a prime candidate is the oil fill tube.

Roger that. Air filter was replaced today. Will try to disconnect the MAF tommorow and take a drive. Thank you for the responses!

I had problems with 1124 and 1126. It turned out to be a vacuum leak. Indie found it with a smoke machine.

Where was the leak?

I dug out the paperwork and it doesn't clarify. IIRC something came unplugged up under the throttle body.
