another possibile item is the converter starting to plug up. If you can have the codes read and have a scan tool that can read the sensor input, check the O2 sensors to look at the efficiency of the converters. Front ones should be moving rapidly from around .1 v to .9 v. The rears sholud slowly move around .4 to .7 Good luck and let us know.



Being way2old is why I need help from younger minds
