I barely got home from work.
If the RPM goes below 2000 it will continue to drop and die. It stumbles and stutters on the highway. I couldn't use overdrive. If I had to stop I had to put it in neutral and keep revving it, then power drop it into 2nd gear.
Fortunately a coworker followed me most of the way home. I had the code reader sitting on the passenger seat so I reached down and hooked it up about 7 miles from home. On the highway it shows that bank 1 is lean and the short term fuel trim is around 35%. That means it is adding 35% more fuel. The other bank reads OK. In town both banks were reading under 10% which is good, but also quite weird since I was still keeping the RPM above 2000. It dies instantly once I stop and let off the gas.
A faulty O2 sensor could give bad readings causing the computer to think it is lean when it isn't but that doesn't explain the hard starts. The O2 sensors have to warm up to do anything.
A bad fuel pump doesn't explain the huge discrepancy between bank 1 and bank 2. Previously bank 2 was the one tending towards lean.
Unless someone has a real good idea of what the problem is, I'm just going to put it in the garage (if I can get it there) and forget about it for awhile. No CEL, no codes.
