My truck failed smog last month at idle. It has been running very rough (rich I think) at idle since I bought it a couple of years ago. Its got EFI. The internal diagnosis said O2 sensor, so I replaced the front one only. I also did the cap and rotor, plugs, wires, and check the timing. I am thinking about replacing the rear O2 sensor. But the front one did not make that much difference, and I am hesitant about tossing in another $70. Any other ideas anyone?
