No codes on the car, Nothing out of the ordinary in any diagnostics except the readings from the O2 sensors which have been replaced early on because they were failing. The first O2 sensor reading is a little all over the place ie:0.07 then 0.755 then 0.100 then 0.645, where as the 2ns O2 sensor reasd around 0.485 plus or minus 0.020 and this may be normal, I do not know. I have looked a the wiring harness in the top of the engine and it seems OK without peeling it all apart. I'm wondering about the knock sensor but I think the engine would cut off or at least get an error code. Fuel pump relay I still have to find but again diagnostics show no problems with the fuel system. Anybody know where the fuel pump relay is on this car. I haven't seen it under the back seat nor under the hood.

Thanks
