My cobalt threw the codes po300 random misfire, po301 cylinder 1 misfire and po302 cylinder 2 misfire any ideals on what can be causing this. Car has basic bolt on and a tune.

 

Did those happen after you did a No Lift Shift?

If not, it could be many things. You could swap the cylinder 1 and 2 ignition coils with 3 and 4 and see if it gives you a P0303 and P0304. If it does that, then it could be bad coils. Could be your plugs too, or something else.

Give us an idea of what mods you have, and if you are tuned, etc. And whether the codes came up during normal driving or during/right after WOT.

 

No didn't happen with No Shift Lift. Codes came up as soon as I started the car in the morning in the garage. Mods are Dejon intake, Dejon upper charge pipe with HKS blow off valve, ZZP intercooler, MPX catted downpipe with full 3 inch MPX exhaust with muffler delete and Trifecta Tuned. Thanks
