I just became a member of the car talk community and thought I could tap into the collective expertise here. I have a '04 4 cylinder hyundai sonata and it vibrates at low rpm. I thought it was an engine miss so I replaced the spark plugs and cleaned the throttle body and put in some fuel system cleaner. My current theory is that I have a leak somewhere in my intake but I don’t know how to start looking. Am I on the right track? The vibration only happens at low rpm, idling is bad. There’s an intermittent rocking and I’m afraid that there might be some permanent damage if I don’t rectify the situation.
Any help would be greatly appreciated,
