ok i have a 94 civic DX and my idle goes from 950 to 1500 over and over, it is quite annoying, i have done the tb coolant bypass mod, but reversed it to see if fluid was going through the bottom of the tb and it is! any ideas, could this be the TPS ? i am not throwing any codes! i have i/e/h and intake manifold.
