Vibration at about 1,200 rpm
Ok guys, i searched, couldn't find anything like mine. I got a vibration only when i get back down to about 1,200rpm. If i rev the car up to anything over 1,200 rpm then let it come back down to1,200 rpm the car will vibrate pretty good and stay at that rpm for a few seconds. After it stops at the rpm, it bgoes back to normal tho. Its weird and my mods are in the sig. I'll check and see if it does it with the stock carb air filter assembaly, but i'm not sure if it stops it. Thanks in advance. God bless

Instead of taking the brace off, install solid motor and tranny mounts. Then you can vibrate all of the time. lol.
Detail the conditions that it vibrates in, in more detail. Is this reving in the driveway, driving at a steady speed, in all gears, does pushing the clutch in and holding the rpms change it, etc..

Nick812, My friend and i put the same engine torque brace on his 7. Go ahead and buy it. It comes with directions the whole way through.

No you don't. Alright, i checked the driveshaft and where its connected to the diffriential, everything was fine. The bolts and nuts were all there and it wasn't loose. I couldn't check where it was connected to the tranny tho because i need to jack it up.

Kory, i think it does slow itself down a little bit when you're off the throttle, but its hard to tell cause where i live the roads aren't that straight. They're either uphill a little bit or downhill a liitle bit, or i don't really pay attention

The only way to properly check the driveshaft u-jpints, is to pull the driveshaft. This is why I asked for details on the vibration. If it vibrates while sitting still, it's not the driveshaft.
I have a brand new brace sitting here and reading the instructions, it addresses vibration. You may need to back off the nuts that tighten down the rubber bushings. Try that. The instructions say to tighten the nuts down by hand until the bushing and washer are just beginning to press on the torque brace, then tighten each side down 4 full turns.

If you raise the idle to 1250rpm that might eliminate the vibration. J/K.

Back the nuts of on the torque brace. Softening the torque brace will lower the resonance frequency. Make it low enough and it will only pass through it when you start the car.
