PearlLex Posted July 30, 2004 Share Posted July 30, 2004 I had been having problems with my check engine light coming on. Then I reset it and it would stay off 100 miles or so then come back on. Tonight after about 1000 miles of being on, it went away. Is this common and will it come back on? Quote Link to comment Share on other sites More sharing options...
jkosasih Posted July 30, 2004 Share Posted July 30, 2004 The check engine light come on only if there is a problem, so when it's on again go stop by at autozone and let them read the code. It is weird after is on and off by itself unless you unplug the battery. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted July 31, 2004 Share Posted July 31, 2004 it is normal for it to turn off and on depending on the problem, it does the same thing after 3 cylces of the engine it is the egr not working properly Quote Link to comment Share on other sites More sharing options...
dcfish Posted July 31, 2004 Share Posted July 31, 2004 Get it coded so we know what the problem really is ? Quote Link to comment Share on other sites More sharing options...
PearlLex Posted July 31, 2004 Author Share Posted July 31, 2004 i have a 96. autozone said they didn't have the right tool to fix it. if it is the egr, does anyone know how much these cost? Quote Link to comment Share on other sites More sharing options...
SKperformance Posted July 31, 2004 Share Posted July 31, 2004 go back, autozone doesn;t realize you have an obd2 system not an obd1 Quote Link to comment Share on other sites More sharing options...
PearlLex Posted August 1, 2004 Author Share Posted August 1, 2004 they looked! autozones tester is rectangular. the diagnostic on mine is circular.... Quote Link to comment Share on other sites More sharing options...
SKperformance Posted August 1, 2004 Share Posted August 1, 2004 you have more than one diagnostic plug the one they want to look for is the one in the dash beside the fuse panel behind its cover. it is rectangular. Quote Link to comment Share on other sites More sharing options...
PearlLex Posted August 1, 2004 Author Share Posted August 1, 2004 that is a tester? i saw it yesterday but i was just going with the plug that says diagnostic on it. i'll try that and let you know. Quote Link to comment Share on other sites More sharing options...
PearlLex Posted August 2, 2004 Author Share Posted August 2, 2004 yep. autozone ran it. its the front o2 sensor. wh00t Quote Link to comment Share on other sites More sharing options...
SKperformance Posted August 2, 2004 Share Posted August 2, 2004 i thought so, they are idiots sometimes. get a motorvac it is cheaper can will improve the overall performance of the whole car as well as gas milage and should clean up the o2 as well Quote Link to comment Share on other sites More sharing options...
