engine shakes

[wruddy]

long story - short - 94 gt stock

Engine shake came on quick.
Done so far....
*Changed fuel filter, plugs, wires, cap, rotor, pvc valve
*clean MAF
*clean K&N air filter
*looked and did not find any vacumn line leaks
*Hook up two cans injector cleaner to fuel rails and ran it thru - improved 80%
*ran two cans injector thru two tanks of gas - no improvement.
*pulled injectors, soaked them in cleaner, replaced one that was not allowing fuel through. Car ran the best it has ever run with no engine shake and lots of new found pickup for 30 miles. then shake came back slowly until it is now shaking so bad I am afraid to drive it.

what next - clean fuel tank, blow out fuel lines, reclean injectors?

Any ideas or suggestions welcome.

if its shakeing that bad i would take off the serpentine belt and check out the harmonic balancer.

How are the motor mounts???

what is the fuel pressure at?

Is there a loss of power? Does the shake vary with engine speed or load? Are there any unusual sounds coming from the motor/trans? Does the motor shake when you take it out of gear? Is there a difference between when you are driving and sitting at a stop?

my vote is for motor mounts... engine movement would be very evident if the mounts suck
