Bogging down and wants to cut off when
you take off, idles perfectly and runs great

bearings in the bottom of the motor? any
ideas on this, anything

The only major sensor on that older engine is the Throttle Position sensor. Have you tried changing out any parts yet?


You may have a bad EGR valve or EGR vacuum solenoid. Have you removed your PCV to make sure the ball bearing isn't stuck? Have you sprayed any Mass Air Flow cleaner into your MAF sensor?
