Default Shaking problem...

man i hate my car
i finally got the distributor put in it and it ran alright, but my plugs were fouled from running so rich so we changed those today... took it out and ran it pretty hard because it was running good.... stopped and got gas and then pulled out and i noticed it shaking.... so i stopped in a parking lot and found that my coil wire was arcing on to the metal on the coil.... so i replaced that thinking that would fix it and it didn't.... its not like a crossed plug wire or boot not on a plug shake because that would make it run bad and it runs fine still but its just a shaking that somewhat goes away at WOT and in other spots its not there.... could i have possibly torn my tranny mount up? or what else should i check?


theres no squeaking or squealing or anything like that... it runs fine but it just shakes like no other....
if its not one thing on this car its another....

try and track down the reason for the lean condition, it's possible the plugs are fouled again. could be anything from spark to o2 sensors making it run rich

an opti runs off a dowel pin unless your opti is installed in the wrong slot or you have a adj timing chain, you timing wont be off unless the pcm is telling it to be.

1st thing i would do is pull a few plugs and see what they look like

How old are the wires? Coil?
Maybe test your fuel pressure too.
