Hello all,

My first post so hello

I've just upgraded from a Vectra B DTi SRi to a Vectra C DTi Sri and I'm a bit concerned by a problem I've just noticed.

When I accelerate in 1st, 2nd and 3rd I seem to get a bit of a jolt that seems to be coming from the front end. The only way I can think to describe it is that its like the engine is rocking back as I accelerate. The car is running fine, no lag or misfiring and you don't really notice it in 4th or 5th.

Cheers in advance

Martin
