i currently have an 04 saturn ion redline that has show a miss fire code 9 times in less than a month. i have taken it to saturn and they did a fuel cleaning treatment on it an it has not help. i need to know what to do. does my spark plugs need changed is my coil pack going bad. please give me some feed back it is getting near the end of my warranty and i would love to get this fixed asap.
Random cylinder engine misfire is the same coe I got on my 06 Ion Quad 3
I've heard evrything from clogged fuel injectors and or fuel filter. I'm waiting to hea rfrom Onstar who has the problem in history and will get back to me.
My mechanic says the problem lies in the plugs or coilpack. They're supposed to last 100,000 miles but he
disagrees.
Good Luck

I have 51,000 miles on my cage and I got error code 300 and 101.
My mech. uses a Solus engine analyzer from Snap-On
