D16Y7 Block/D16Z6 Head - - - Stumbles @ Idle
So im pretty sure i did everything right, used the cam gear from the Z6 head got it all timed up nice and beautiful and readjusted valve lash, no clicking whatsoever :). The problem is as follows; motor will start and idle beautiful all day and rev up like a dream. When I let off the throttle the RPM's drop below 500 and it hesitates/stumbles for a 2-3 seconds then resumes the idle. I am rather baffled as to what is going on, possible fuel pressure regulator? MAP sensor? Whats going on?
