Alright were to start, i had a y8 motor on my 98 civic ex, with p2p ecu. Now here's were the problem... i had to get a swap=jdm d15b for my over heating issuses with the y8, blown head gasket. Now the swap was not to hard is that i already know that i had to swap my dizzy for wiring issues, but did not know i had to swap out my old y8 intake mani, and my old y8 knock sensor, and my fuel injectors. So now by taking off the timing belt to put in the knock senser... i think the timing went off by doing that or my engine needs some serious tuning. So now driving the car is a *** car is slow as a snail... wtf. Taking off from first gear is crazy car wants to stall i would have to double clutch it so i could jump the rpm a little *** and when i try to run it  ("I COULD OFFICALLY SAY THAT MY CAR IS LOUD FOR NOTHING") the rpm,and the mph gauges moves slow. I also brought it to autozone its throwing codes like system is running too rich, knock sensor is defective, and o2 sensor for my intake. So now my questions is what could be making my car run sluggish like that... any good advice,tips,knowledge... it would really help, i need my car to go to work/school ASAP... thanx
also im using my p2p ecu, could that be a problem??? v-tec is also not kicking in @ all???  

what codes are you throwing?
