I'd recommend checking the fuel pressure. You'd most likely have a fuel trim fault with a bad regulator. Did you swap the injectors to see if the misfire followed?

well, before i cleaned out the injectors I tried to narrow it down to 1 cylinder but couldn't, out of 6 CEL's i had 1 P3001, 1 P3002, and the other 4 were all P3000.
Today I tried to trip the CEL again and I had 1 P3001 and 1 P3000. When I cleaned the injectors they all ready 14.2 ohms of resistance.
I'm not really sure how to go about checking the fuel pressure but I'll do some research and check that out. Thanks for all your help and suggestions.
