2001 3.0L running lean and running rough at idle
Not sure what the issue is but runs rough at idle especially at cold start has codes for lean on both banks and resting idle is running high around 1000-1100 rpm
Lean condition on both banks sounds like it could be a vacuum leak or bad MAF. Something is letting unmetered air inside your intake. Loads of help on this topic, check hoses and intake manifold for leaks-- I found one on a hose that had gotten old and wasn't sealing around a barb fitting. Took care of bank one's lean condition, now just gotta figure out what's going on with bank two!
