This is for an idle from 1,800 to 2,000 RPM in neutral and continues on when you shift so you can imagine what it sounds like. I have had the coolant water temp sensor changed, ACT sensor changed, PCV Valve changed with PCV valve mess and rubber grommet. A while back I cleaned the thottle body and IAC and that helped but this time it isn't helping? Any ideas what it could be?
