Morning another issue I have with the car since I bought it is very jerky when coasting. does this sound like a driveshaft issue? if it is I'm lip cult enough to have a pair of brand new shafts sat in the garage just wondering if people think it's this before I change them over. cheersThumbs up

More likely engine mounts with excess movement maybe? Wouldn't imagine shafts cause a jerky-ness.

Shafts gone will cause gearstick shake, not jerkyness.

As Devere says, either engine mounts or a misfire on coasting causing excess engine movement.

the gear stick does shake. it's at low coasting revs say around 1.5-2.5k under load there's no jerkiness and at high revs none. still sound like mounts?

Under load is where you would find gearstick shake if the shafts had gone. Yes

Well I have a full set of vibratechnics mounts I may try swapping them over see if that helps. just I was told that they'd been changed before I got the car. but maybe they have already failed Thumbs down

Top mount broken where it bolts to the body, as per the seemingly common failure?

Could be, but that is usually accompanied by a 'click' sound when going on and off the throttle.

The gearbox and top engine mounts were changed when I had it, not new items but ones from the grey car!
I did have a look for cracks in the mount but it didn't appear to have any when I changed them bud

I meant a misfire whilst the engine was off gas, probably rather unlikely but just looking at all avenues.

Is it actually a misfire or is it just a bit of popping on the over run? What exhaust has it got? Or is the whole thing relatively standard?
