<HR style="COLOR: #666666" SIZE=1> <TABLE><TBODY><TR><TD vAlign=top width="100%">This truck has had a hesitation upon exceleration problem of which I am unable to find the cause, since I bought it.(1 yr ago) I just replaced the carburetor due to a flooding problem and now have two other problems. 1) truck will stall once it comes off high idle (cold) until it fully warms up. 2) truck runs rough at idle all the time, 3) it still hesitates upon exceleration.
The choke was adjusted as per the carb specs and it operates from fully closed to fully open as it appears that it should. The truck runs fine at road speed after it is fully warmed up. ( except when stopped at idle ) I have tried various choke adjustments with no change

Anyone have any Ideas?

New parts: timing chain/gears, distributor, coil, fuel pump, plugs, wires, modulator
Checked for vacuum leaks and traced line placement (as best I could ). Egr seems to work as it should

Thanks
