Try replacing the oppise 02 sensor you have a heated 02 sensor thats out, and it is possible the new one is defective or it may have what is called a lazy 02 it does not shift fast enought for the computer.

Normally what I would say is: Yes, shot gun a coolant sensor into it as they are relatively cheap and it would narrow down your options. Next I would say look at the MAF or airflow sensor, whichever it has. However, I just did a quick search through Alldata, and it says that there is a recall for the PCM because it needs to be re-programmed to read the O2 sensor correctly. Also there are a couple service bulletins relating to updated O2 sensors. The very first thing I'd do is check to make sure that the PCM has be reprogrammed. This was a recall and should have been done for free.

Hi
I cant tell you why but I do have a solution for you to try, I had a similar fault on a fiat punto last year, I disconnected the battery for an hour and then put it back and the car started, Im still puzzled by this but It may work for you, worth ago, make sure you have your radio code before removing the battery
Hope this helps
Regards
Dan
