so its registration renewal time for me and my boo failed I/M test and these are the codes it threw
P0300 Random/Multiple Cylinder Misfire Detec-
P0301 Cylinder 1 Misfire Detect-
P0320 Ignition/Distributor Engine Speed input
P1294 (No description)
My local mechanic says that replacing distributor and spark plugs wll fix first 3 codes
and
P1294 is not a factor in passing or failing test
is this true or no? he didnt do anykind of diagnostic on my TJ - only looked at the trouble codes
