Alright so I have two problems and im not sure what they're related to,I think the first may have something to do with plugs but;I have a stick shift 1991 4runner and everytime I am in gear and lift off the gas my car starts vibrating and making a low deep sound kind of like the sound it makes when you're going off the highway,so i think that may have something to do with the plugs..And my second question before im about to put it in gear and i just barely dont have the clutch in all the way it makes a sound like a dying ewok and does that for a while so if any of you have any input about it let me know! Thanks!

 

have you checked the u-joints

 

nope i guess i should..thanks

 

I hate to touch this one too bad but the dying Ewok sound could possibly be weak damper springs in the clutch. If that is what it is you will know for sure soon. When one of them comes out and chews up your clutch.

Check over everything in your driveline REALLY good. Wiggle everything that moves. If you notice any play in the driveshaft joints, get them repaired as quickly as possible.

 

Oh yeah and I forgot to tell you it's a hydraulic clutch
