hi i have a N reg compact and it idles really bad, like it has parkinsons!! i changed coilpack and plugs and throttle sensor position switch and air flow meter and im going crazy!! i even changed both o rings on all 4 injectors! diagnostics says knock sensor but im beat!

ill personally kiss the feet of the person who solves this 1

Would say you have a bad air leak. there is a crankcase vent valve on the inlet manifold. follow the breather pipe from back of cam box to inlet manifold there is a diapram in it that will be perished. change pipe and valve.
