My engine slowly started running rougher, it has gotten to a point now to where it shakes the entire van. I've replaced, timing gear and chain; much needed, water pump; started leaking, t-stat, fuel pump, rebuilt the carb, double checked all vacuum, replaced EGR, repaired any possible ignition wiring problems to where this thing will shoot a spark over 3 inches, and am about to shoot this thing. It does have over 500k on it, however the compression is between 149 & 148#'s on the cylinders, what in #**# am I missing. I'm out of options here.
S.O.S
P.S. Please help me keep it from going to the crusher

Ignition Dura Spark or TFI-IV? Put vtiming light on marks do they jump around? Power breake does it miss, bustup at 1500-2000rpms?

It has Dura Spark, timing mark doesn't jump and all dist. Components are tight and seem to be working properly. All vacuum has been plugged and checked one at a time. I can take it from 600rpm to around 4500 and it has a quick responce and vibration decreases but is still present. Upon decreasing the shake comes back. I did notice however yesterday, a whistle when it coming back to idle but I cant pin point where. I was not driving the van when this started so I can't get a clear answer as to what was going on when all this started. It doesn't smoke and all plugs looked normal, but I replaced cap, rotor, wires, and plugs just to eliminate anything possible. I have had another older mechanic look at it & even he walked away shaking his head. This is truely a new one on me. I really appreciate your help and will donate to the site as soon as I can get this thing back up to where I can turn a dime again. I'm in home repair so I'm dead in the water right now.
