I would check that. I thought the digitool's reading would tell me that but I didn't get the instructions with it. And apparently the ECU is bad. First time I used it the engine started missing at about 3k, second time, months later, it ran fine. This time the missing is back. Rats.

I thought there were really only two sensors, 1 wire and 3 wire. Some off brands but I got Bosche.

Thanks,

Mike
