Hi folks,
I am extremely frustrated with my 1989 Bronco II with the 2.9 engine(5 speed manual 4wd manual hubs & transfer case if that matters). It was 100% fine one day, then literally the next day it wasn't. When accelerating it's sputtering and losing all power. It Usually starts and idles fine(some times with a noticeable miss), but once I start to accelerate it starts sputtering, and if I push the throttle more it stops sputtering and completely cuts out. Also backfiring through the intake. I let off the throttle it resumes running, but will resume sputtering when given throttle again. It progressively gets worse the longer it runs, then it idles really rough touch the throttle and it dies. Don't touch the throttle and the rpms slowly go down till it dies. Some times you start it back up and it idle fine till you try to drive. When it's sputtering there's a smell, I want to describe it at raw fuel but not quite.
I changed the fuel filter then removed, tested and cleaned the injectors to no avail. Went on to the TPS and tested it with a multi-meter and it tested fine. Checked to see if the distributor was loose and it wasn't. Changed the TFI, plugs, new plug wires, new coil, and replaced the profile ignition pickup(PIP) in the distributor, no dice. Cap an rotor still looked fine. I read on another forum about a 2.9 with similar symptoms, someone suggestred to unplug the O2 sensor and see if it went away. I tried this too with no change.
These are the codes I'm getting(if I'm interpreting it correct)

Please any help would be appreciated. I really love this little Bronco, but it's driving me insane.
