Where is ICM on 1990 civic hatch w/ 1.5, still having acceleration problems
Just bought 90 civic great car except mid range rpm rough running,after about 2300 rpm she takes off smoothly I tried swapping dist. throttle body ,map sensors from another civic and it still has this problem. I do love the challenge of figuring it out w/o dealer help but am getting discouraged. The plug wires are fine as is cap, rotor, denso plugs,etc. check eng light does come on some times if I really push it (like up a hill) but light is not on all the time.
