Re: SES light again

The exact code would help, as noted above. Not necessarily the MAF sensor. The 97's seem to have a problem with the pink wire that supplies +12V to the MAF harness connector. You could pull the connector off, and check for 12V on the pink wire with the key in the "on" position.
