Missing out only when accelerating

[netnews.insightbb.com]

My 1986 Dodge is missing out when accelerating. It runs smoothly when in
park and does not miss out at all when stomping the pedal . But in drive and
trying to accelerate moderately it misses out bad. If you accelerate easily
and once up to speed it runs fine. Any advice on what to check?

Thanks

fuel filter will be my first point to start.

PS: does it have injectors, if not, our accelerator pump might be bad. try
to see if it is working fine when the car is not running if you have
carburator.

If the spark plug wires are going bad, you might need to check them also.
One of my friends car is missing when the car is on load.

good luck.

I agree that ,IF you have not changed the plug wires recently or
ever , do that first. If you have trouble with acceleration on the
highway, reaching 60 smoothly and/or stumbling and hesitation when
steady crusing on the highway, probably the fuel filter. Good Luck
