Ok i try to do search but its temp down..so if you have link to it or just can give me the advice real quick i would appreciate it. Ok..i help put in a H22 into Ek9. He converted from Obd2 to 1. Everything runs...but haha. Idles at 1500 so to high, when he switches a vac from manifold. It drops down, then when he drives then stops the engine dies. Now he doesnt have Intake pipe hooked up right now, cause just testing the swap. Would that play a major role. I dont think it will but maybe. Now i told him to check all vacs, and idle screw. He also had problems with distributor wiring. If you guys can tell me the link or tell me the diagram for the distributor wiring for h22 into Cx hatch. Now another question. Hes going to put on my vafc on it and was wondering a baseline setting or conservative setting if anyone can help with that. Thanks for all help.
