I feel like my car has drive line lag or slack. When I let off the throttle and get back on it really quick, it takes a second, and I feel like everything underneath me move then comes back into the same place and then I start moving. I don't have the turbo manifold support or the intake manifold support because the previous owner trashed it. Also the bar that runs underneath the transmission is missing. Do you think this has anything to with it? All replies are greatly appreciated.
Driveline lag?

Try this:
Get under the car, grab the driveshaft. Now try to shake it, both side to side and front to back. Now after you've done the hokey pokey, ask yourself this: "does my driveshaft move excessively?". If so, could be a number of things, such as the center carrier bearing (common to wear out by now) or the bolts holding it to the differential being loose.

your not talking about the tranny mount are. You???? Also check your engine mounts....

I had the same thing, IJ told me to do this and it was my diff...jack up the back and put on your e-brake and tranny in neutral, then try and turn the driveshaft, if it moves excessively then your lash is coming from the diff.
While it's up there try putting the tranny in gear and e-brake off and doing the same thing too, if the lash is from your tranny that will show it.

Looking at your profile, says you have a 90, so I'm assuming the round fluid filled motor mounts that are notorious for failing...
i think hes talking about the cross member that runs right under where the tranny meets the block.

Better off having a friend hold down the brake pedal to apply the disc brakes. The e-brake shoes have about 1/8" of rotational slop when they're applied. This will show up at the driveshaft as alot more slop. I figured this out when I checked my car on the 2 post lift one day, with the e-brake set, then checked it the next day on the 4 post lift (with the tires chocked). My diff was less... sloppy.

Yeah, it's kind of more under the motor though, right? If that was missing it would probably make the car handle weird, but not cause driveline lash.
Easy way to tell if the trans is the problem. (Manual trans) See if the lash gets better in 4th gear, compared to all the other gears. If it gets a little better, that's normal. If it gets ALOT better, you've got bearing wear in the transmission. 4th gear is direct drive and the bearings have less effect on the lash since it doesn't use the countershaft bearings and loads the input/output shafts differently.
My trans does this (alloy plate W58). Straight weight 190 gear lube is holding it together. That and a clutch that hates launches and melts down at the suggestion of a clutch kick.
it's most likely your diff lash, the differentials in the mk3 are notorious for it because Toyota used a crushwasher instead of something more durable to hold the tolerances.
Mine has always been horrid, and I've never fix it.. thankfully I don't beat on my car, but I imagine it isn't too great for the various components over time :shrug:
