Just tested my vacuum pressure, and it was a steady 14 psi at idle.
BTW, this was tested right after a 15 minute drive, and the engine was still hot. It was in park, too.

I still think we should buy a good Fuel pressure gauge with a long hose and drive around to get a proper reading. I kinda don't trust the cheapy Harbor freight gauge I bought.

Any way of scanning to check numbers on the TB electronics. Perhaps you have a funny IAC or MAF.

Something like 19" would be normal for N/A,,, Do you mean 14 inches of vacuum or negative 14 psi?
