Need Help with 1990 SR5

[Supertom1969]

Here is my problem. I just put a new engine in my 1990 SR5 3.0. New Block, pistons, Rings, Rods, Crank, Heads, Valves, Cams. I got it all back together and running fine, until the second day and now when I push the throttle down it will die, That is pushing it when I am in gear and start to go. But if I am in park and stop on the peddle it will hessitate and then rev up. If I barley push it while in park it will die. I don't know where to look for the problem. Please help...

Thank you in advance,

Tommy B.

We rebuilt our 90 3.0 and had similar problems. Ours turned out to be miss plugged vacuum lines. Once we got all the lines properly routed and seated, the engine ran fine.
