i don't know how to set the spark timming. can u please inlighten me on how to do. i'm at work so when i go home it's me and the civic toe to toe. is the cam timming and the spark timming the same procedure?
It could be mounts, however if it was it wouldn't stop shaking. It's most likely timing like 1stGen said. To set timing you need a timing light. I've never done it before but I take it you remove the timing belt then set the crank pully and cam gears to Top Dead Center TDC and then you use the gun to I guess set the timing on the distrubutor or something?
With the engine running you need to put the timing lead on the #1 cylinder spark plug, loosen the distributor mounts and twist the distributor housing until the timing marks line up like they tell you to in your repair manual [you do have a repair manual right?]. You will be pointing the light down at the crank pulley, and the marks will line up with a scale on your timing belt cover. You don't have to reposition the timing belt or gears any specific way. If the engine runs fine, the cam timing should be fine, just check the spark timing.
