2000 Jaguar XJ8 V8 Two Wheel Drive Automatic 114000 miles
I have been receiving intermitting P0121, P0175 and P0172 but mainly P0121 codes. When I am driving on the streets the car goes into failsafe mode every couple of blocks and doesn't ever go into failsafe mode on the highway. When I turn on the AC that problem goes away for a while but when it comes back I only get a P0121 code. In the winter the lower valence was torn out by high snow and I wonder could this be the cause. I have replaced the throttle body and I am due for a oil change and the car runs good until the failsafe mode jump in. Need to know what is next as far as repairs? And what is the actual issues that need to be addressed?
have the same problem?
