Mixture problem??

[kerondav16]

Hi Guys

We have finally got the Nova back on the road through a MOT and running fairly well, when you have stop acceleration and lift off the pressure it wells like a misfire but it is good with pressure on the gas is this still a mixture problem?

Also we wish to upgrade the basic 1.2 solid disks to a larger vented disks do we need to change the front hub? We are going to run Corsa 15" steel wheels for now so brake disc size is not a problem

Thanks in advance for help

The front hubs can stay as they are, you just need the calipers and the carriers they attach to from another vauxhall. Astra/Cav 2.0 ate calipers with 256m discs are a popular and very good choice.

What engine is it? Carb set up etc. Modified?
