Eric i have a 2002 Maxima which has a rough/misfire type feel. I have no codes. I have taken it to the dealer and their initial look did not come up with anything other than it’s possible that my connectors to the ignition coil (since they are brittle and old) could be loose and causing an issue at the idle. Under normal driving conditions and at highway speeds all is ok. If I put it in neutral/park it does not do the stumble. I have replaced all of the plugs, cleaned out the throttle body, replaced all of the coils, cleaned out the MAF, and checked for vacuum leaks. I’m replacing the connects soon, but was wonder if you have any other advice.
thanks in advance.
