Disco shaking, please help!
Hey all,
This is my first post but I've been on many many times as I bought an 03 SE7 in October of 19. I have run out of ideas for what could be next on this shaking issue. Like many threads before I have shaking at 30mph at about 2100 rpm, deep shaking, then it tapers off around 45 to a quicker lighter vibration. Nothing when I let off gas. Seems like very faint miss at idle maybe. Nothing at all before 25-30. I put in new iridium plugs, nothing. I put in the front drive shaft from Lucky 8, no help (but good to know I'm not tearing up the transmission!), yesterday we tore out the intake manifold and change coil packs and wires that I got from luck 8, (seems a little better but definitely still there at 30mph). I do not know what to do next!
Thank you all for any advice!

Possible you shock absorbers , the problem is they as so heavy you can just push the wing down a check the bounce but it easy to take them off and and then full stroke them in and out to see it there is any give, when in the full in and full out positions, if one if lost gas /oil it will bounce more than the others
also lets not forget some thing a simple a wheel balancing if the weights have come off your wheels will vibrated out of balance, always best to check the easy inexpensive stuff first

New coil packs, new spark plugs, new wires. I'm thinking Fuel pump, revs fine in neutral but flooring it in drive only gets to 3000 rpm. Feel like it could be struggling for fuel. Seems to be the next step. People are saying that is a common fuel pump symptom? I'll look at mounts, struts are newish. Do have a p0126 code so a new thermostat will be going in also. Could a fuel pump/clogged filter or a bad thermostat cause the engine to go into a "limp mode" during driving so no more damage is caused?
Thank you all!
Thank you all!
