Check Engine Light Quandry ???

[Rage4order]

Ok, two weeks ago I put on a new mid pipe from the exhaust manifold to the muffler, Previously to putting this on I had a check engine light. Put the exhaust in and two new O2 sensors and it ran like a gem, til today. On the way home I noticed that the dam check engine light was on again. The only thing that I can think of it being is maybe one of the wires to the sensor came loose. Havent been able to check it yet.

Anyone have any other things I should take a look at or suggestions. Any advice would be appreciated.

Get codes. Come back then. Codes will be very helpful.

ok, stopped at the autozone and hooked up the computer and got a P0141 O2 Sensor heater circuit malfunction bank 1 sensor 2. I then cleared the code and the light went out. Im sure it will come back on. Hope to check it this weekend, supposed to have some decent weather in Pgh.

Usually if its heater circuit problem, the O2 sensor is bad...... If you can, get the O2 sensor that plugs directly into the socket...... The universal ones (the ones you have to splice the wiring into the old harness) have never been very good as far as the heater circuit goes...... I've installed hundreds of those, and the car usually comes back within a couple of months with the same problem....
