#7115, "RE: Strange fuel trim values.." In response to In response to 9
MAtt, what do the O2 counts look like? This happened on my sisters 3g. Same exact issue, running pig rich. I scanned it with the scanner and the o2 was claiming very lean at idle. As a result the ECU raised the trims to 113% at idle.
When you look at the trims make sure they are cyclig back and forth. I noticed hers was pegged at lean. Even if the ECU is raising trims, the O2 should see a constant lean-rich-lean-rich ect.
