Hey guys,
I was coming off the motorway yesterday in fifth, I needed to slow down so changed into fourth, when I put my foot on the clutch the revs started rising to about 4500, I put it in neutral and the revs would maintain 4-5000 revs! I drove for about 800m and every time I changed gears the revs would rise to 4k. I managed to pull over and stall the car to turn it off, but even in neutral the car would rev very high without my foot on the gas! Very strange.
I left the car off for around 40mins, started her up and was fine! Even went to Penrose and back with no issues.
My car is an 82 E21 - m10 1.8 carbureted. I've done some research and think it could be a vacuum leak from the manifold - but couldn't find anything loose.. Possibly m/t fluid.. not sure If anyone has any knowledge around this or knows anyone that could have a check it would be much appreciated.
Cheers guys.
