Glad you quieted it down and got it running better. So you didn't mention it, but I'm assuming you also fixed the injector O-ring leak while you were in there?

Yes, vacuum leaks large and small are the cause of many of the problems with the fuel injection system.

Yep, O-ring is back and now it runs like a top.
