Vibration Problem 1996 Plymouth Breeze
 

Hey Guys, new to forum. I inherited an 1996 2.0L Plymouth Breeze from my mom. I have a problem with a vibration that comes up thru the steering wheel when I am at idle in drive or reverse. It is much worse when the AC is on. So far I have changed plugs, checked vacuum lines, cam sensor, crank sensor, and I just tonight took the throttle body out including idle air control and cleaned everything. The car runs slightly smoother but the vibration is still very much their. I am not sure where else to look. The steering wheel vibrates pretty bad. Does anybody have any ideas? Thanks.
