Can you guys tell me where to look under the car?



I think it is broken because the last owner mentioned something about it and when I go real slow from a stop the whole drivetrain shakes sometimes



also i have nitto 555s for the street and when i shift into 2nd gear it doesnt hit hard it feels padded



i dunno I could be wrong but the weird vibration in the car bothers me when going super slow from a stop ive never felt or heard a noise like that before

i have no braces anywhere on the car yet just the strut tower one



anyone have pics of broken ppfs?

Jack up the rear end of the car and get under there. The PPF connects the differential to the transmission. Just get a flash light and examine it thouroughly.

I was also told to check to see if the pressure plate bolts are tight



See what happens is when you take off slowly it feels like your are stalling and the engine is about to cutoff but it's not that since I have sufficient rpms. it just shakes and makes a weird noise but that noise comes from the front of the car where the clutch would be



I will do it this wednesday when I have time

do I really need to jack up the car? can i slide from the rear under the gastank? It should be right behind that correct?



Also, does anyone have a profec b? can you tell me what the 3knobs on it do? I am running .84bar 12.2 and i want to go to around 13.5

1 bar is 14.5 psi right?



thanks!

I belive that 1 bar is 30psi.

Anyway,, if your PPF is cracked the tranny will "jump" violently is the crack is bad. Your gear shifter would be acting as though it is going to jump out of the car..

Spounds like you might have a slipping clutch but its hard to say without seeing the problem with my own eyes.

1 bar = 1 atmospheric pressure at sea level = 14.7lbs/in2 or I think that's the way you say it... I don't know everything either...
