Subject:      O2 Sensor Questions
Content-Type: text/plain; charset="iso-8859-1"

I've been experiencing some engine troubles over the past while with my 85GL. Upon acceleration my engine hesitates and stubles with no power. I checked and cleaned the AFM, made sure there were no air leaks, replaced air filter, and put in a new Temp II sensor. After all this it did idle better and run well. When it was causing all the problems it happened to be very wet outside, eiter wet snow or lots of rain. I assumed it must be an electrical connection somwhere. Well today the hesitation started again (crappy here today.....wet, snow etc.) I immediatly pulled over and heard the engine stumble and run bady. I then disconnected the O2 sensor and all is well again. Could it in fact be a screwed O2 sensor or the wire that connects it to the ECU???? I'm not sure of the age of the sensor. Also, upon pricing a new sensor I got some different results. The dealer here (Ont Canada) wants $140 for a new one. The local autoparts store has one in stock for $50. It is not a Bosch but he says is made by Bosch under the name "Neumo" (or something like that). The list vendors want ~$30US. What should I do. Lastly, is it bad to be driving the van with the O2 sensor disconnected???? thanks, Chad
