Hello and Welcome to JustAnswer. I am reviewing your question and will be back with you in just a second.
Most dealers will charge a diagnostic fee, most auto part stores will check it for free. I have seen a good number of cars with misfire codes lately. As well as some failed vvt valves, air fuel sensors, and ignition coils.
But you will need to know the diagnostic codes to further diagnose your problem.
Is there a sequence that the PEP Boys folks need to perform to get their sensors to work with my car? They tried several sensors and none would work with my car.
Im not sure what kind of diagnostic equipment thet are using. Most scan tools can retrive check engine codes. You may try Autozone or Advanced auto parts to see what they say, if there is one close by.
Hi. Sorry for the delay in responding. I never had to take the car to the dealer. This has happened twice in the past 8 months. I had been using generic premium gas with no additives. I just filled the tank with premium gas plus additives and the lights went out after several miles.
I hope this information can assist you and others. It appears that the oxygen levels are setting off the engine lights. Have you had others with this issue? Someone at a dealership told me about this fix.
