Default few more questions

how do you get rid of the AWFUL vibrations once you get going fairly fast?

will a 95 lt1 throw the egr codes and set off the SES light?

4th gear jumps out after the car has warmed up? bad synchro?

slow as ***** i beat a riced out fart can civic yesterday idk what all he had but i seen 3 gauges on his pillar i beat him by 2 car lengths the first run and then by a fender the second run. why so slow? or is it faster than i think and he is possibly FI? i couldnt hear ****!

car rumbles like it has a cam in it loud and obnoxious? any way to check without pulling it apart to see?

i think thats it.

is the speed sensor in a 93 m28 different than in a 95 t56?

What kind of vibrations??? Is it at certain speeds? Is it constant? Does it progressively get worse then go away?

Could be a number of things. I had a weight come off of my driveshaft once and it cause a horrible vibration from 80 to 105 then it smoothed out a bit but was still there. I got the DS balanced and never felt it again.

Sounds like your driveshaft is out of balance. Take it to a drivetrain shop and they should be able to balance it for you. It is cheaper if you pop the driveshaft off yourself and take it to em...

^yep sounds like driveshaft to me also! You can get it rebalanced for about 40-60 bucks depending where you live. Some will say get an ls1 driveshaft, but to me its a downgrade on stregnth. Balance the stocker or buy an upgraded unit imo.

nah, if you want a cheap fix, pop the DS off yourself...doesnt take much...upgrade the U-Joint if needed...take it to a shop and they will balance it for like 40-60 like king said...re-install. Good as new for less than 100 and maybe 30 minutes total of personal labor.
