Background: I’ve had various DTC codes over the past few years: 0446, 0133, 0441, 0440, 0130, 01300, 0420. Car has 188,000 miles.
I had both O2 sensors, MAF sensor, fuel pump and filter replaced, PCV valve cleaned and a tune and vacuum leak fixed 20K miles ago but was still getting codes, P0130, 0300 and 0420.
In the last couple of weeks I’ve been getting P0171 (too lean Bank 1) which appears about 8 miles after code reset. Additionally a couple of days ago it stalled and only started with starter fluid spray. I found a leak (water spray) where the air intake manifold joins the throttle body and fixed that. Also recently noticed hesitation when accelerating which was getting worse. Car stalled again. Couldnt get started. Started next day then later didn’t start.
Was also getting P0420, 0446 and also 0133 codes in the last couple of weeks.
Any input? Vacuum leak, fuel pump, filter, fuel injectors? Battery seems OK and it ran for several seconds with starter spray so I guess electricals ok?
I have another vehicle so I have time to try and get it at least started on my own.
