high on gas fumes
- Sep 21, 2003
I've got an issue I can't figure out. After idling for a few minutes, the AFR will slowly go lean until it reaches -- on the AEM gauge and is showing 18.5 in the PL. Fuel pressure isn't dropping when it does this, and I've adjusted the IAC and TPS to read where they should. There's a MAF translator with an unknown MAF, but the previous owner set the base switch to "85mm sensor" . Also, the o2 sensor was replaced recently. Just got the PL installed on this car(newly purchased) so I'm trying to sort out all the problems the car came with. Here's an idle log with a couple revs. Thanks.
