Hoping to get suggestions on my problem. For the past month when I first start the car up in the morning it will be misfiring with the CEL blinking. I'll drive it like this for about 2 miles shut the car off for about 20 minutes. After I let it sit I restart the car and all seems normal (CEL still on) like there's nothing wrong. The CEL test reads Multiple misfires in a given period of time. I've checked the fuel, disconnected battary for 2 hours to reset computer, new plugs and coils with no discoloration or residue, unplugged maf no change and looks clean. Checked fuses all good. No idea what to do next I like to fix my own vehicles and trying to avoid paying a shop. Only thing I can think of is a bad tune (stage 2) but it's been fine for the 6 months I've had it. Any suggestions?
