Re: 09 Patriot exhaust/converter
My first course of action would be to have the computer scanned and checked for codes at an autozone type place or with your own hand held scanner, theyre cheap. Once you find the codes go online and research the heck out of what might be causing it. You might find that the problem might be a bad sensor or even a faulty gas cap. As far as clearing the code after the repair has been made, the cheap obd11 scanners have an option to erase all codes. This can also be done by removing the positive battery cable for a while but the scanner method doesnt make the car have to learn all over again. On a somewhat related note, I know someone who had a cel lit for a bad cat converter on a 4 cyl nissan. The mechanic suggested a fuel additive that was supposed to cure the problem for a while so it could pass inspection. Its been a year and its still working fine. I dont know the product but Im sure you can google it. I dont usually buy into those quick fix additives but it worked for them. Worth a shot at least.
