as an update so far only changed the 3 spark plug connectors (under the coils) myself and car's idle has improved a little or it may just be in my head. Car has not since hesitated like it did before. Only drove car a few times since but, the hesitation was randomly occurring anyway and time will tell if the connectors were the culprit. Next I am planning to change the plug wires and maybe even the spark plugs since I will be there anyway. In the process, I did notice oil in places that didn't amuse me though. On the #6 spark plug connector (closest to the firewall) and in all of the places I have circled in the attached picture. This pic is not from my car, but I found the pic online. The left two holes connect to the air intake and the other one is at the throttle actuator I believe, which all should be dry I thought. I know with my luck it won't be something simple like the valve cover gasket, but you guys have any ideas whats causing the oil to be there? or is this normal?
Took car to two different exhaust shops that only change exhausts and I figured out they do not have an emissions tester. One suggested I add a fuel injection cleaner to the car, but I don't trust those additives.
