Transmission 'shunting'

Post by Mk3alan »

Using the old girl on a 65 mile daily route has highlighted a problem!
The CD starts fine, ticks over great and goes well, but, if I am creeping along in a queue in first or second and clutch fully engaged at about 1000 rpm the drive can be jerky (shunting?) causing me to dip the clutch to stop it.
Seem to think this might be something to do with fuel pressure? Never checked and don't know what it should be.
Any ideas?

That sounds quite normal to me.

It would simply indicate that you are just not giving enough oomph to the engine to give it enough momentum to crawl along.

I suspect it would be even more apparent if the car is fully loaded (heavy car), ascending a gradual gradient or if the hand brake is slightly dragging, you are in the wrong gear or the car has only a small, weak or poorly tuned engine.

If it was a fuel pressure issue, then I suspect it would struggle at higher revs.
