Ok, I'm getting pissed off about this issue.
Driving to work last week the car started to misfire about 15 minutes into my commute, I grab the xcal and it read P1132 LACK OF SWT RICH
So I checked plugs, wires, etc...and pulled the MAF because I've suspected for awhile it was an issue, the misfire went away through the RPM range but the car barely idled. Replaced the MAF with another KNOWN GOOD unit from another 95 T-Bird 4.6. Car seemed to be a lot better the next day, until about 15 minutes into driving when the misfire returned. I drove to work and pulled codes again P1131 LACK OF SWT LEAN P1132 LACK OF SWT RICH
Both codes are HO2S1, so I instantly assume its the O2 sensor on bank 1 (drivers side)
Car idled like shit this morning, first time driving since I put in the new O2.
Pulled the ECU fuse, plugged it back in, still misfiring -- P1132 P1131 both returned.
