i recently did a sohc zc swap into my 88 civic hatch dx, i got somone to do the wiring changes, and we are having trouble getting it to run right, it starts up fine, it throws a code for atmospheric control sensor or whatever. but it is idiling at 500 now, and when we give it gas is usually shuts off because of too much fuel, but when we took it from the shop the guy did wiring for us, it ran fine and we drove it home on 3 cylinders, we had to get a new injector and seals, but now its just not workin right. any help please. but all the sensors are in tact, but we arent positive about the eacv. please help
