Engine light came on!

Driving home earlier I get the engine light and the car start shaking and the engine light keeps blinking. Do anyone know what is wrong? I am running jb4 map 5 and just changed it to map 0. I tried turning the car on and off but the shaking still persist.

2F6C Exhaust fumeflap, input signal
29CF Misfirings, cylinder 3
29CD Misfirings, cylinder 1
30BA DME digital motor electronics, internal failure
29CC Misfirings, several cylinders
0000 Failure location not implemented

Change the spark plugs already and still getting mis-fire. do I have to delete all the codes before starting the car?

Coil packs and or injectors need to be replaced.

I think coils are $35-45 each from Tischer IIRC. What you need to do first is swap the coils so you can pinpoint the problem. There are details in the mentioned sticky on how to properly debug so you're not wasting money. And you should clear the codes after doing any work, otherwise you have no idea when they were triggered.
