After replacing the intake manifold gasket a second time the car hesitates to run ,very sluggish, and no power. Help.
RE: I’d check all your connections, vacuum lines, etc, for any problems. If it ran fine before you did the intake gasket, something obviously went wrong there. The gasket could have possibly moved out of position and caused a vacuum leak. Maybe a sensor wasn’t hooked up, etc. I’d recheck your work.
