Ok, something else is going on besides KR. I installed a boost gauge just to see what I'm dealing with. I have had a few times today where the engine sputtered and lost power, this was driving normally not even getting to 10in/Hg. I drove about 100 miles today. I've noticed that the engine sputters (it only sputters when Im off the gas) then if I drop a gear to bring the revs up that after a few seconds it recovers and everything is fine.
I did get on it once and it hit 10psi, I let off immediately. I drove around a little and got on the freeway but didn't let it pass 5psi. The car seemed to be great,
I set the cruise to 70 played with the HUD and drove the 20 miles to my exit.
The exit is a drop to about 45 and then a overpass over a rail system. Then a light on the other side. I made the light and swung through the left hand turn as I straightened up the engine sputtered and my pucker factor was high as a Constable sat at the light waiting for me to sputter and finally it came back online.
So it's fine the rest of the way to the office and all the way back. Then I exit the freeway and as make the turn it sputters and dies, throw it in neutral and start it it sputtered and died again I was able to get it to run but as soon as i put it into gear it died. I rolled into an advance auto (closed) and shut it off let it sit for a few seconds. I restarted it and it seemed loaded with fuel. It cleared up and I drove it the rest of the way home. I pulled #5 to see what it looked like and it's brand new, maybe a little lean. Didn't mess with the others too hot.
It seems like the fuel pump is getting uncovered, but I have 3/4 tank. I had something like this happen before and it had something to do with the fuel pump piping internal to the tank.
