I've got a gti6 engine in my 205 and it's got a horrible flat spot at around 6k. It accelerates fine and then at 6k in 4th it just goes flat sometimes if I back off the throttle and ease back on you can feel it try and pick up again Any ideas?
Previously had a filter on the throttle body do I've installed a airbox and cold air feed thinking this will help but doesn't seem to have altered anything. Also timing is ok (all lines up with alloy pulley fitted)
