ok so my 88 lo3 is acting weird after a ingniton control module and a map sensor swap , both are stock replacements , it will start but idle very rough and the lights inside surge and does not burn fuel completely " kinda like a miss-fire , now when i switched out the ICM there was two cables one white and the other green , could a mix up in these two wires cause this " wrong terminals connected " and /or could it be my map sensor , for a moment i thought it could be that i would have to hand-crank my engine and set it to #1 TDC on comp. stroke , so i did it and i think im correct because if i was off on the whole #1 TDC thing it would start at all , any ideas of what i might have done wrong ???

It can be off on the TDC and still start and run, but not well.

ok , i figured out the problem , i hooked up the wires wrong on the ICM , now , my engine idles high and shakes " not alot " but more then before i installe dthe parts , could this be due to a mess up on the whole TDC thing ?

As long as the timing is set properly, should run like it did. If it was 180 out, the car would not run.

hmmm , its shakes the car even more when i throw it into drive , it didnt do that before the parts swap , what could it be , also the high idle , above 1000 almost 1200
