I had a loose PS O2 sensor. I didn't discover this untill yesterday. I drove the truck 300 miles thursday and got the code 44. Tightened the o2 sensor, cleaned codes ran some errands. Running like shit again, code 44 again. Swapped the O2 sensor out for a known good sensor, put the sensor that was throwing the code in a 4.2 drove it around for 30 minutes. No codes in the LWB with my O2 sensor, still getting #44 with the "good" sensor from the LWB. I did my best at testing the plug that the O2 plugs into, I got roughly the same values between the plug on my SWB and the LWB. I am not sure what else there is to do. Ive done everything short of checking fuel pressure. The ignition module has not been relocated from the distributor, I have not had any issues up until the arrival of the warmer weather. Truck has all new ignition components, a new TPS and I cleaned the MAF last weekend. 1181xx miles. The truck idles terrbile almost to the ploint of stalling out. Runs good on the road plenty of power etc, so it seems its getting fuel and ignition. It will intermittently loose power in town and low speeds. Does this truck have a VSS, I am unclear on what that does. Thanks for any insight, I have run out of ideas and the RAVE hasn't helped.
Anyone think an alternator could cause all this?
I might have a 91 Hunter for sale soon.
