I just sol my evo and bought my first cobra....and im loving it so far, but after two weeks of owning her ive got a cel code of po171......anybody run into this problem,and have any advice on a quick fix?
Yes. I've seen the code before. I believe that is a downstream O2 sensor. If the car has the stock H pipe, get the O2 sensors checked. One is probably bad. If you have an aftermarket offroad Midpipe then you need a mil eliminator or a tuner to shut them off.Lovely97cobra said:I disconnected the battery and cleaned the maf for starters, went through tons of start cycles, and here almost two weeks later the light came on, ran the diagnostics to find the same cel code p0171.....if an o2 sensor was bad, would it really take that long for the ecu to register again?
It's how the sensors are. Mine use to take about a week before they would trip. Don't worry about it. Totally normal. MIL eliminator work, but a tuner is better obviously.Lovely97cobra said:Car has bbk straight pipes to magnaflow mufflers.......if I needed mil eliminators, why when I bought the car, it took a month for this code to first pop up, figured it would have been on or come on quicker than that.....this is all new as im coming from the evo world...
