Howdy James,

Welcome aboard!

You have already gotten some good advice, and my take agrees with many. The O2 sensor is suspect.

It makes sense to me - before you do anything else - to isolate the O2 sensor, and see how she runs. With the O2 sensor disconnected, if the engine is warm, and all things are well elsewhere OTHER than the O2 sensor - the engine should perform well - all gears, cruise, start, stop, whatever mode of operation. This will tell you for sure that the problem is in fact the O2 sensor system, ie, the connections, the wiring, the sensor itself. NBow you can trouble shoot. You see, the O2 sensor is simply not required except for fuel efficiency, and if iO2 sensor is out of the circuit, that is the sensor and ECU are not connected, the ECU will drop into a default mode and the engine will operate just fine. The fuel economy will be off just a little bit, however. But it will identify for sure the system that is at fault. Check connections very carefully, reconnect, and try again. If the engine acts up, then test the O2 sensor as prescribed in Bentleys.

Good Luck,

John Rodgers 88 GL Driver
