I have a 55 plate 1.9 sportive it goes fine as long as I'm accerlerating or off the throttle but if I try to keep a constant speed it gets a strange rattle that I can only describe as a pinking sound the van loses power and smokes but as soon as I accelerate again its fine?
It starts fine and ticks over perfect. I cleaned the MAF and EGR out no change, anyone got any ideas? Thanks in advance
