I purchased this car in October of last year. It runs like a champ and has never given me a check engine light. Shortly after purchase, I replaced the battery with a new one. When it was inspected in May, there was no check engine light, but it threw the codes for the O2, EGR, and thermostat sensors. The exhaust system and the thermostat were replaced. The EGR was tested and did not show any problem. The car was then driven 50 miles. When tested after 50 miles, emissions test read "Not Ready".
So, the car was driven 250 more miles--same results. The county where the car was inspected allows only two codes in order to pass emissions. At this point, the state capital was called. My mechanic was told to replace the EGR despite no Check Engine Light. Turns out the EGR was malfunctioning. Car was driven 300 more miles and was tested--NOT READY. Capital then told mechanic to run it through the ODBII instructions to reset the computer. Car was ran through twice and was tested--NOT READY.
The capital granted an Emissions WAIVER after that. Should I replace the PCM?
have the same problem?
