1/ Have you fitted the spark plug leads in the proper firing order.
2/ Look inside the top of distributor Top (this is not the first time a new distributer cap has very small crack) or the rotor arm is fitting the cap properly. Hope this helps Best Wishes, Malcolm Campbell.

SOURCE: whining sound from under van only when i push the gas.

The serpentine belt is the most common cause for whining sound when accelerating, try to understand if noise is coming from serpentine belt.

Also check power steering belt under steering column, and also the rotor and chain, thei do not make whining noise , but can make noise when accelerating.

The belt is first suspect.

SOURCE: low power when accelerating

I thought the filter might be the issue here, on carb cars the engine tends to stall out with a plugged filter.

Check your catalitic converter, you might start with an oxygen sensor first. your local muffler shop can do a temp check on the converter for you, but you can replace the oxgen sensor your self pretty easy.

What's missing ? Fuel ,spark , compression ? How many miles on the vehicle ? Does it have spark , pull a plug wire while cranking an hold it near a good ground . Put a fuel pressure gauge on the vehicle , is there fuel pressure ? Do a compression test , 150 psi . engine mechanical problem . timing chain .

New plug misfire in dodge ram 1500 6 cyl van


could be your coil, but can also be internal, have you replaced both the air & fuel filters ? if so, dump some good fuel injector cleaner into tank when half empty , top off with 91-92 octane fuel, see how that works for you, do some highway driving, stop & go traffic creates problems, todays fuel w/ethonal is bad for older cars, be sure to have code cleared from ecm !
