DarinJ Yea I saw them there. I'll have to take it off again tomorrow and try again maybe without the lower 4 bolts in. Thanks

Jerry Bransford There are some fairly subtle positioning studs on the head that the intake manifold has to be properly positioned over for there to be an air-tight seal. Together with Island TJ, I too suspect that it simply is still not seated properly... this is a common issue and it is nearly always caused by the intake manifold not being quite properly positioned.

IslandTJ Sorry I did mine over 5 years ago and don't recollect ... Perhaps someone will chime in...

Hard to say, I did it that way (having the lower 4 bolts in) when I replaced mine and didn't have any issues. I also opted for a better Felpro gasket and did not use the cheapo gasket that came with the new manifold.

IslandTJ I suspect your manifold is not fully seated...it may not be correctly aligned with a stud.

DarinJ It's a 99. Vacuum lines are good. Reset ECM by disconnecting neg terminal? If so did that. Throttle good. Wtf

Are you sure all vacuum lines are on and not leaking/pinched.. Also sounds stupid but if your drive by wire try to reset your ecu.. If not drive by wire make sure cable is not holding throttle open
