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.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Checked the voltage on the MAF, and it was reading and fluctuating a bit (but I don't have a clue what the reading should be).

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

History - 62K 2000 C2. Got the ABS/PSM lights a few weeks back. They stayed on for 50 miles, stopped, and returned again 275 miles later. I then cleaned the MAF. 250 miles later - CEL light. Not flashing. Just lit. Pulled the code - P1128. Reset the code. O2 sensor readings looked OK. Big wave before the cat. Little wave after the cat. Checked the voltage on the MAF, and it was reading and fluctuating a bit (but I don't have a clue what the reading should be). Immediately upon restarting car after restting the code, ABS/PSM lights come on again. Drove a few blocks, filled up, and the lights are still on. So, I was thinking, bad MAF. Just replace. Any other ideas? Clean it again? Many thanks in advance.
