Hello All,
Newbie here. I have a bout of throwing some rich codes. (posted below) and wanted to see if you experts could help out. FYI, I have the 3.0L engine with about 28,500 miles on it. The check engine came on about a 3 weeks ago. I looked at the codes, and checked on this site for possible issues. I started the diagnosis process on the air side. I cleaned the MAF and erased the codes. After about 200 of city/hwy miles, the CEL came back with same results. I wanted to add. I changed the fuel filter about 5000 miles ago. All plugs with correct gap and coil packs were changed about 2000 miles ago). Air filter was changed less than 5000 miles ago. I haven't checked anything yet on the fuel side, i.e. pressure, leaks, etc. (I also included a full scan result after the fuel trim report) Thanks everyone. I'm looking forward to hearing from you. Have a great day.
*I cleaned the MAF
*checked the power and ground connections from the car to the MAF plug, (all good)
*ran logs on the fuel trims, each time CEL came on, the negative values were just about the same, (posted one below)
*I ran 4 redline tests to check the numbers on the MAF. I didn't take logs, but in 2nd gear at about 6400rpm's, the MAF #'s were 98g/s and 102g/s the first day, 124g/s and 108g/s on second day. that is a far cry from the 80% of max HP (220 x .80=176).
*did a smoke test to check for vacuum leaks, found a hose just past the MAF, that had leak from original crimp clamp. Replaced that and after retest, no leaks anywhere.
