Hey everyone just joined today but I've been browsing for a while now. I have been having a small vibration on my steering wheel when I am at a full stop in the Drive possition such as a red light. I can also see that my tachometer is a little jumpy from time to time on a full stop in Drive. I changed my fuel filter, all oxygen sensors, new spark-plugs about 20,000 miles ago (Ngk Platinum lazor) , new air filter, new pcv valve. I even cleaned the inside of the intake and put a new gasket on tight. Any feedback would be great.
