Ok, I was on the freeway, was running in 5th at 3k rpm then i punched to 5k rpm and shift to neutral when all of a sudden my idle drop very fast to 500 and lower i thought that it died on me i couldnt hear the engine so i hit the gas and it rev, and when i was at a stop light the engine and idle felt very rough, then the ecu leds turned on, and some weird code started to show
here it is what i picked up

DCC1: Long Light...
DCC2: Long Light...
then reapeat after 5 to 10 min both lights at the same time

I checked the code list and couldn't find anything similar,
I also checked for intake leaks, loose connectors and everything is ok.

This happened 2 days ago, now it seems to be ok I hope.

Any suggestions??
Thx Max
