Have a 96 ford ranger which detected the code after failing emmissions..ford told me that i needed to repair the o2 sensor, canister purge, mass air flow sensor, & catalyst converter, and also changed the idle control valve..did that and problem still remain..also got a P0300/random misfire code..which after replacing the parts the dealer also said it will fix the misfire...did not fix the misfire..now have mechanics telling me to replace the PCM..please any suggestions...im thinking maybe EGR valve..HELP!! |
