idle and vtec issues
All right i have 98 integra with a jdm b18c in it and a p28 ecu.in August i put the motor i have now in the car.i put a new wiring harness in the car which was the same one i had before i got a new one cause the original was in rough shape.i start my car and i have to blip the throttle so it will idle correctly and still then it idles at 22.0 afr on my innovative guage,but once i drive the afr is fine.if i engage vtec and come to an idle my car will idle surge and go lean again.i can turn my car off and restart it it will go back to normal sbort of the lean afr.i checked all sensors all vacuums and did a compression test and except for low readings on my fan switch everything reads and checks out fine.i have no check engine light on and it works cause i see it when i start my car and my ecu wiring harness tune is all the same.i'm lost on this one any help would be greatly appreciated.
