Ok, got the motor installed and running. The thing fires right up and idles smooth (strange for a XP cam) LOL but it is idling at 1100 - 1200 RPM. All my vacuum is correct, I had an issue with my fuel pressure regulator vacuum I had running to it was wrong but have since fixed. Now when I shut the car off I hear hissing under the hood for a few seconds like pressure is being released. I started the car back up, sprayed carb cleaner around the vacuum joints, nothing. Cut the car back off, sounds like the hissing is coming from where the EVAP quick release plugs into the EVAP sensor. Anyone have this problem? Aeroforce pulled the two codes P0463 and P1643. If it was just the P0463 I'd think the sending unit was bad, but with both codes I'm thinking I have a bad leak at the EVAP hose to sensor. Also would this cause a vacuum "leak"? I hear it hissing, but I don't smell fuel... :-/ bit confused.
Fuel gauge is acting like a bad sender per the P0463 code. But I've researched that the EVAP has something to do with function of the level indicator....
