Hi! My Check Enging Light came on today. So I checked what's the CEL codes. I had more than one code. I think one of it is #27. I really don't know if I read the codes right. The codes flashes in this order:
1 2 7 2 1 3 5 5
Is this mean code #27 and #13??????

Then later I went to Autozone to use the scan tool to check. I got 2 codes. one is about I got a bad O2 sensor. and second one it said:
"Injector High Side Shorted Together"

What's is this mean? Do I having problem with the injectors or the harness? How do I fix it?? Somebody please help me out. Thank you very much!!


By the way, I got Hahn Stage 2 turbo kit in for about 6 months and I'm only using stock injectors. Also I got 5 speed tranny swapped.
I think the car runs OK with the CEL on.

Can any one help me??? PLEASE!
