Do you think that the van is in the right gear?, i.e. is it chugging at low revs, rather than being high revs, but accellerating slowly.

I am assuming automatic transmission here, but one thing to check is that the auto transmission is correctly adjusted - and this is a quick, cheap thing to do anyway. I only say this as this is how i solved a "low power" issue on my van. http://www.igmaynard.co.uk/bongo/forum/ ... =3&t=53432

the problem with forums is that a little knowledge is a dangerous thing, and people like me, with the best will in the world, only see problems that they have solutions for, and we will be wrong 90% of the time!!!

as to the smoke, no idea buddy! might it be the cold? I trust you have read this
