Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I'd try cleaning the MAF first, and see if that fixes it.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

99 M96 engine. Ran amazing coming home from the last track day (maybe too good?). Started running real sluggish the next time I drove it. I drained all the fuel and refilled. Still runs the same. This morning on the way to the track it started surging a lot under acceleration, feels like its dragging an anchor and tops out at around 5600 rpms at wide open throttle. At partial throttle it will slowly climb to 7200 rpms. A couple miles from the track it finally dropped P1128 and P1130 codes. Any suggestions for trouble shooting out here at the track?

POST 2Original post

That's an O2 sensor error, but it could very likely be caused by a dirty or failing MAF. I'd try cleaning the MAF first, and see if that fixes it. If not, then replace the MAF. After that if you don't want to keep hunting and pecking, take it in.

POST 3Original post

clean throttle, idle control valve..... might also be dirty/bad maf, cats or 02 sensor. I would do one item at a time though. My .02.

POST 4 / ORIGINAL POSTEROriginal post

Turns out the block off plug for my resonance chamber had fallen out. So the maf wasn't sensing all the air the engine was getting. I plugged the hole again and its not cutting out anymore but its still not running very strong at all.

POST 5Original post

After the repair you'll need to reset the ECU to clear the codes and remove the erroneous fuel trim values stored. Disconnect the battery for 5-10 minutes and reconnect it to clear everything and start fresh. It will take a few miles to relearn everything and get back to normal. Shawn

POST 6Original post

Just make sure you have your radio code handy BEFORE you disconnect the battery. You will have to enter your code after you reconnect the battery.
