No I have barely any money in this so far.(spark plugs, some used oem coils and injector..) Whoever owned this before me was having the same issue and thats why they sold it Im sure. They broke all the injector harness not taking clips off and many other amateur things found...

It had no codes when I bought it from dealer. I drove it 350 miles and then got a 301,302,300,420,430. I fixed air leak in the resonator by the maf sensor. Disa valve and valvetronic motor also had air and oil leak.

All the codes then went away except for the 301. Switched coils and code did not change. So I then removed fuel rail and cleaned all injectors. The first injector was clogged and sparked for no reason while spraying. I then swapped that 1st injector with the 2nd injector and then received the 202 code which i never had before. That was proof enough for me that the injector was bad. I then got a new used injector and put it in the #1 spot and now still have the 202 code.

I tried and cant even get a testlight to light up 12v in the unhooked injector wire harness with the key on....I did check all injectors ohms and they were consistent at 12.7 i think. I have an appointment at a good garage this monday. Even if i figured out the new 202 code, I will still be stuck on the 301 code...

Thanks for trying...
