My GC 2000 threw a 3002 code saying the #2 plug was misfiring and I changed them all. The code then said 3002 done but the Check engine light still remains on though it shows done. How long does it take or how do you clear the code? The reason I ask is that I have to get it inspected by NY's damned new internet connected inspection system and there can't be any codes showing. Thanks, Driz

Did you pull the codes yourself?
I think you have to use your scan tool to cear stored fault codes. At least all the vehicles i have worked on you use your OBDII scan tool to clear codes. I havent got into a Cherokee yet, only have had mine for a year.

just another tip. if you have the codes cleared then you will have to run it through a warm-up cycle a number of times before the OBDII system scanners at the testing lanes will let you through. her jeep had an evap code in it so we dumped the codes with a scanner. two days later at the inspection lane it failed due to not enough history base for the computer to judge a pass/fail rating against. he said that if it had a few more cycles on the history it would pass fine. just fyi...

a simple way to to cleay codes is unplug the ecu and leave it un plugged for an hour and a half i heard about on a web site and then i tried it on my friends XJ cause he had a miss firing problem too and then when we plugged the ecu back in it works just fine. all we need to do now is put in new rod bearing and a new edlebrock chock
