knight02 Posted July 18, 2004 Share Posted July 18, 2004 Could someone please help me with these codes and how to fix them. I got these codes after running the scanner. My 95 es300 is idling rough and check engine light is on. Didnt have any problem prior to this. I'm thinking it's the MAF switch or meter, but not for sure. Please help me. Thank you in advance for your time Quote Link to comment Share on other sites More sharing options...

blake918 Posted July 19, 2004 Share Posted July 19, 2004 Random misfire is usually an igniton problem. I had "random misfire" on my LS, and new plugs and wires saved the day. ;) Quote Link to comment Share on other sites More sharing options...
