Intake Manifold Gasket Problem
I have heard that the 2.3L have issues with intake manifold gaskets going out. Today i changed the passenger side spark plugs and while i was at it i decided to test if mine are bad. I completely sealed off the throttle body with my hand and it continued running fine. I even opened the throttle a bit with the other hand and it revved up a bit. It would only rev up maybe another 1000 rpm and then it would stay there no matter how far i opened the throttle. When i would take my hand quickly off the throttle body it would idle down and almost die, one time it did die. So would it be safe to assume i need to replace all the gaskets on the intake system?
