How to check for slipping clutch disc do the following. Rest the front of your DeLorean up against a fixed object like a tree or a wall. Put your transmission in the highest gear, in your case 5th gear, and slowly let out the clutch pedal. If the engine wants to die then your disc is grabbing well but if the disc continues to slip then it needs to be replaced. I heard this on a helpful radio show called Car Talk in the U.S.A. Here's their web site http://www.cartalk.com The two guys call themselves Click and Clack the Tappet brothers. Their real names are Ray and Tom Magliozzi. Mark R. Vanyo.

When driving in third or fourth gear at around 2000rpm, if I accelerate hard the engine rpm climb as the speed increases up until around 3000rpm and then suddenly the rpm increase further to around 4000rpm with no increase in speed. After the sudden jump the car continues to accelerate gradually until the speed meets the rpm of the engine. It does not happen every time but is happening often enough that I think its a problem that is going to get worse. Any ideas. Paul.
