Poor acceleration
Hi, my v70 2002 has poor acceleration and the engine sounds “tappy” any time I add more throttle.
I can cruise on the motorway but if I give a bit more throttle to go up an incline it accelerates slowly and the engine sounds “tappy”
It’s like the mixture is too rich and there’s no performance at all.
Also if I really boot it up to 3000-4000 revs there’s a puff of black smoke out of the exhaust.
I have Vida but no codes stored.
Anyone have any ideas or pointers for me please?
Thanks all.
