and beside that, on my ford turus 98, I have p0156 , what can be wrong with it.
I think that's your 02 sensor, those are pretty easy to replace once you locate them, I would check at alldata online they should have a detailed description of the error code with a location for the sensor. I am pretty sure that it's an o2 sensor but do not know what the exact location is on your vehicle.
I have an 03 that has started stalling- manual transmission- and has popped an error code P0441. It goes off and comes back on. I thought I had fixed the problem by replacing the gas cap as it went off for about 2 months- but the light decided to visit me again last night. The car has a bit of a rough idle....can it all be related and if so, what is recommended to look at for a fix?
