Timing mistake?

Timing mistake?
Ever since I messed with my timing, when I crank my truck up it cranks and revs up to about 1200 rpms then drops to 500 and it does this about 3 or 4 times then when it finds an idle point it shakes at idle

Suggest you remove, clean, then reinstall your IAC. Then test it per instructions on this link: http://www.fordfuelinjection.com/?p=39
Error code scan result's would prove helpful!

Sorry I have a 94 f150 302 MAF with a 4r70w tranny. When I bumped the timing I unplugged the spout, marked my stock timing, loosened the distributor up, turned counter clockwise until I could see maybe a centimeter of clean metal then tightened it back up, cranked her up used the timing light to see the timing, killed the truck and put the spout back in. I had to put it back to stock timing using the same method and now when it cranks the idle bounces a couple times and then settles down

A cylinder/tube looking thing bolted to the drivers side of the throttle body right behind where the intake hoses attach to the TB. I don't know how to check the idle without a tach though....so hopefully you have one.
