Yes I meant before. And no. That’s what’s weird. It’s running it’s best. I’ve tuned with a vacuum gauge a million times. This motor and others. Always went for greatest, steadiest vacuum and got the best idle as a result but this is different


After a 15 mile drive last night, got home and it was running fine. No more stumbling up the driveway. Wonder if it was the vacuum leak? Or the 35 year old alternator? Both were fixed over the weekend. I put in a new one wire (old one was under warranty!!!!)

Great, maybe some fouled plugs,and/or low ignition voltage causing fouling? Always nice to know the resolution.

Well, this is a classic case of fixing too many things before checking if it worked

I cleaned the spark plugs and re-gap them, That didn’t solve the problem.

I fixed the intake manifold gasket leak, and also got rid of the 35-year-old incorrect alternator, now it seems better, so I’m not sure which of the two it was
