Thanks, Ron. Laurel isn’t too far, but with the car running like this, I’d be a bit stressed driving it around the beltway. Maybe I will call him to see if he might have any ideas. I wonder if the manifold itself might cause a vacuum leak. But it has both water and air passages, and oil, so I would think that if an air passage were leaking, then so would water and/or oil passages. I have no leaks of any kind, though. No only is the idle high, but when I throttle up, the RPMs increase and stay high,making it a bit of a scary drive. I imagine there must be someone in Tysons Corner that works on old Ford cars. Does anyone have any info re? Thanks.
