Hi I have a 2000 neon with 2.0ltr with a 155,000 miles. I am having problems with a rough idle and a running lean condition. I replaced upper and lower engine mounts, which where ripped apart as well as the trans mount that ripped as well! Still, after replacing these mounts car still runs rough at idle and in gear! And when the i put there air con on, it gets wores! I changed spark plugs gapped to 0.36 and new wires coil is in good shape and change oil to mobil 1 10/30. also, im getting oil in the front manifold where the throttle body connects to. I change the pcv valve, and still im getting some oil down there! why? Can anyone help?
