Well it was an intake manifold leak. I went ahead and updated the intake manifold while I was at it. And I figured while I was doing that I might as well go ahead and do the PI intake swap for more horsepower.
I took the Idle Control Valve off and it still looked clean. I just replaced it last year. I also checked the vacum lines, they all seem to be tight and there is no hissing sounds that I can hear where there would be a leak. I do have quite a bit of ticking noise coming from around the fuel...
same problem different day
I fixed that.:(
It threw some codes at me last night. Too lean Bank 1 and too lean bank 2.
I had a friend of mine with a really nice code scanner come over and check it out.
