My 92Dodge van B150 With a 3.9 started acting like I was
running outta gas the other day.I was on the highway doin 70 and felt a hesitation,its been doing it since.
I have to flutter the gas pedal to get up to speed,if I try to accelerate too much, it back fires and keeps bogging down.Its hard to get her up to 35 or 50 but once I'm there, its ok.
I,ve given it a tune-up
replaced fuel filter
checked the coil
replaced fuel pump
taken off converter

She idles fine and I can rev it up,no problem in park and nuetral.But, put it in gear and it feels like its running outta gas as soon as I hit the pedal.
Every thing I've done so far it has needed anyways,But now I dont want to waste money on a part I dont need.
What should I check next?

HI:

First, I would have the computer scanned for codes. Your problem could be one of several. If I had to guess without being there, I would say to check the map sensor. Try to have it scanned and see if there are any codes. If you have an Auto Zone near by, I know they will scann it for free. I'm sure other parts stores do the same.

Let me know what you find.
