I have a 95 honda civc, rebuilt from ground up, got an allignment, balenced tires, new upper and lower ball joints, and all mounts are TIGHT, the car shakes only when I'm on the throttle, what the heck could it b?

The engine is misfiring. The key here is "only when on the throttle".Quote:

Make certain the injector connectors are secure. Also make certain the spark plug wires are fully seated.
Who did your rebuild?

You're making this one difficult...Quote:

Yeah, a tire out of round/begining to separate, but that should have been picked up when the tires were balanced. Worn steering components: again they should have been detected while the alignment was being performed.
Another possibility: mis-aligned engine. If the front dirve axles aren't loaded properly due to engine/cradle misalignment, that could cause a wobble. And it'll be tough to detect.
If you think it may be this, try loosening the lower engine mounts slightly and shifting the engine one way or the other and drive it. See if you get any change, better, worse, same... Good luck.
Lets say that my motor is missalligned, wouldn't it wobble all the time, when my rms are higher or lower the wobble stops, she wobbles any where from 4-7 grand, and it drives me nuts, me and my buddy did have to replace the main tranny mount, which does raise suspision, don't it
When you apply toque to the axles, the way the power is transferred through the inner tripot (CV) joint is what I was referring to as a possibility.
Is this a new engine and trans assembly with axles into a different body?
I don't know what all was done in your "rebuilt from ground up"
What was actually changed and what was left alone..
I bought 2 cars one shell, one totaled but the motor, I reused the mortor and cv joints, also a couple tires, but the shell I bought the kid cut the tranny mount, so we outlined the mount as it was, airchizzled the spot whelds and put in one off another car, my buddy seems to think the motor might have a lot of tension when I'm on the throttle on the back mount, we had to twist and shimmy th motor to get all the bolts to go throgh the mounts, like I said uppers and lowers were redone, as well as berrings, now my right(passenger side) cv joint leaks out my tranny oil, but I'm replacing the input seals on both sides this weekend, if it were indeed an engine allignment problem, how do I know/ fix it
Let me know, I got nothing to do but wait, and fix, Thanks
When you say "try loosening my lower mounts" do you mean my stiffeners? could that affect anything? let me know
The mounts are designed, through a combination of features, to support and isolate the engine vibrations. Not bind it in place.Quote:

I recommend you have a collision center (body shop) that has a frame machine and accosiated experience to properly inspect your mounts. They can use available data to pinpoint where a critical dimension is incorrect. You have to rule out some potential areas so you can concentrate on the others.
All right then I guess ill have to put up with it till then, thanks again mr rich
