I just had my shift solenoid replaced at a transmission shop. He told me I needed a new o2 sensor. I had the car for a few days everything was great! Really happy now I had my car fixed. But when I was at a stop light and I it turned green when I pressed on the gas it seemed like it was running out of gas or something the RPM's were shooting up and I pulled over to a parking lot and my car turned off on me. It wouldnt start for about 3 minutes of trying.

At that point I heard a DING and my check engine light came on. Got the code
P0129 - Generic - Barometric Pressure Too Low.

My question is: Is this an O2 sensor? Because it would be telling me in the codes that it was right? People have told me if it was the oxygen sensors it would have a bad idle, bad gas millage and a few other issues

I was looking into this and someone suggested it being a MAP Sensor or a CAM Sensor?

Has anyone else had this issue can they help me?

 

My 2002 3.5 Intrepid exhibited the same symptoms.Stalling,RPM's would go up and down and poor performance which was corrected with a new map sensor.Very easy fix.The part was $89 at Auto Zone.
