I have a 1989 1500. Its wanting to bog down as soon as I hit the throttle and slowing down its wanting to cut off. I have rebuilt the throttle body, new plugs and cap and button, new fuel filter, checked all the vaccums, checked injectors, fuel pump sounds like it comes on good and strong. It runs like a clock as soon as it gets some RPMs up. Just getting there is the problem. Let me know if anyone has and suggestions.
