im new to this forum and u all seem pretty helpful..the things u have always suggested have worked..well today i was coming into town and my check engine light came on agian..thats the fifth time this has happend..so i take it to the dealership..still running so they can get a fresh code off there..everytime they say its running to lean except the first time..the car threw a code that said a injector misfired?....they have called gm and gm says to just flush the car..and now they are saying to replace the o2 sensors..has anyone else had this kinda problem?..i have a 06 2.4L with no engine mods..and it has around 12000 miles on it...the problem started at 9000..each time after they reset the light it comes on about 2 weeks later
