i own a 2000 civic hatchback and i just finished puttin a ls vtec into my car and for some reason the car barely drives i have to rev the motor up for it to move and it breaks up alote and also nuttin on my cluster works but the fuel and temp can anybody please help

 

first thing i would do is get it tuned.. what ecu are u runnin.. is ur timing rite.. etc.. all grounds hooked up

 

yea everything is correct im running a jumper harness to a p28 but i think its my engine harness my frieands are telling me that i have a si dash harness and i have a dx engine harness so right now i dont kno wat to do

 

did u wire vtec to the dx harness and the p28 is a single cam ecu u need to go get it tuned sounds like electrical.

 

no i ran it straight to the computer and when i did that it made the car run like crap

 

yeah then def get it to a shop u need the ecu burnt most def bc ur runnin a single cam ecu on a dohc motor. but i would get a schematic of how to wire vtec into the harness not hot wired into the ecu...

 

sounds like a good idea thnx
