I have a 96 dx civic with a 93 b18a1 5 spd. I have all wires connected properly and I know the check engine light is on due to no crank sensor and no 2nd O2. I'm using a 96 integra ecu now and it runs slow. When I install the 1.6 automatic orignal ecu it runs like a raped ape but has a dead spot right at cruising speed. So I want to install a pr4 or a pg7 which one would be better?
