car idles rough at stop lights and chugs sometimes at around 45mph but runs pretty good at high rpms and highway driving. took car to jag dealer and was told i had a bad coil and a bad injector. changed all 8 coils and spark plugs and the bad injector and it still runs like crap...also changed fuel filter valve cover gaskets, cleaned the throttle body. my mechanic is stumped and so am i.. the dash throws no engine lights or codes...does anyone have any ideas what might be causing this rough idle...very frustrated right now/ thanks for any help
