the car starts jerking when i go over a bump or hit a pothole , only for a second and the rev counter drops to zero as i lose all power but comes back to life quickly afterward anybody know what this might be cheers

 

sounds like it a electrical problem check all connections mate and ohms on sensors do the wiggle test on the loom as maybe a broken wire

 

Could be ecu feed multiplug, mine done the same!
Cheers shaun

 

Defo sounds electric problem, check obvious things like coil connection also, as said the wiggle test is going to be most use here.

ya its after getting really frequent last night so the wiggle test should hopefully pick it up

 

Yank the steering wheel adjustable reach in/out a couple of times, there can be loose connections there.

 

I suspect the CPS from what you said also about the tacho, the connector pins often loose there grip, again the wiggle test would confirm this.
