The car: CRX The Motor: B16a1 The problem: at a sustained speed the car kind of stutters. Example; when driving in 3rd at 40 MPH the car “feels” like its not hitting on all 4’s. Then I increase the throttle just a little bit and it feels right again. Cliff notes; at sustained speed in any gear and any speed the car runs crappy. As soon as I accelerate it perks right up. Runs and accelerates perfectly. My first thoughts are spark. I put new plugs and wires, Still sux. I’m thinking the distributor cap next. The coils tested ok(resistance test). After that maybe something like a bad injector IDEAS – any other suggestions starting with easiest ones to check, going to hardest appreciated.
