91 g2500 vandura 5.7
My van was sitting a couple of years before I got it... Ive replaced the fuel filter, air filter, oil change, plugs cap rotor and cables, throttle position sensor, throttle body injector... hers the problem while it has gotten better it still exists. Hunting for idle while in park sometimes dieing. When in idle the throttle response is good, but in gear moving down the road it acts like it's bogging down especially when cool 60 degrees out... does not want to acceleratei pump the peddle to "find the sweet spot" then stay at that rpm 1400-1700 to speed up slowly... any help would be appreciated. I've been told fuel pump but wouldn't it pump the same in gear or in park (N)

John, maybe is the same problem I had. Before you spend $12,876 trying to fix the issue, check the coolant temperature sensor first.
