Hello All!

I finished up replacing the cylinder head yesterday and have ran into a problem. I have poured through the factory manual and have tried everything I can think of. I'm sure it is probably something stupid as that is my luck!


Symptoms:
Engine starts perfectly, idles great....press the gas more than 5-10% and it wants to bog down/ die. Very lightly press the gas and it will rev all the way to redline if needed. Other than that issue, nothing seems to be wrong!?!?

I have checked the following....
-TPS- adjusted and functioning.
-Vacuum- Cannot hear anything/ checked with carb cleaner/ checked with gauge, holds 22 in hg at idle.
-Replaced fuel filter
- checked fuel regulator...good
- Fuel pressure...good since it will go to redline?
- checked crank timing...perfect.
- checked ignition timing...good.
- checked MAP sensor
-Checked every connection....twice
- Pulled every vacuum line and re-set.

I've got about 12 hours of looking at this engine...I'm out of ideas! Help?

Thanks

Is this under load, or free revving?

free revving...I haven't checked under load.
