Codes Return - MAF?
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.
