So i got a 2007 ss/sc cobalt very nice. problem is i get a misfire when it is warmed up. or when i am driving i had my scan tool hooked up and im getting small multiple misfire when letting off the gas but it keeps changing on cylinders. so im confused.... i cleaned my maf, did a compression check, fuel injector balance test and it has new ngk plugs. its got good power, but is jumpy somtimes out of 1st and second lol. i have a scantool i hook up in my car and it records up too 24 hours and does it by trips.but im still not seeing anything lol. also it has 160,000 but you couldnt tell. . i also cant wait to sart building her up.

 

Am I reding this right?

You're getting misfires while coasting in gear, foot off the gas?
