My 03 300 has developed a ticking noise at idle,as you throttle up it goes away,then chop the throttle afew times it revs down and dies.
I have read of the rattling noise due to pv out of adjustment.This is not a rattle but a ticking noise,sounds like an exhaust leak,but doesnt seem to have one.Any ideas? Thanks.Bty,it has weak power at low rpms,then hits hard mid and top.
