Hello,have a 95 ply voyager with 155K miles. 2 yrs ago had head rebuilt.1 1/2 yrs ago had tranny rebuilt.6 months a go had a rocker ar wear out on #5 cylinder.Problem is runs rough first thing in th morning.When it does this trans doesn't shift right,like it doesn' have the right rpm's to shift.Sometimes it works ok though.Sounds lik a fuel delivery problem to me.Also have changed plugs and plu wires.Fuel filter changed a year ago.Start fine on 1 st crank.Whe problem occurs the idle speed goes up and down by 250 rpm's.Any idea ??? THANKS A
