SOURCE: My van seems to be having random multiple misfires
First,investigate the warranty,as there is no need for you to be spending money out of your pocket if the warranty covers such items.As far as the misfires,they can be caused by items a little more in depth,although the spark plugs are the first items to check and replace.The spark plug wires can also cause misfires,as well as coil or coils,and injectors being dirty and partially plugged up.If your engine utilizes spark plug wires,replace them,as they will leak voltage when old,and cause misfires.Anything beyond that will require more diagnostics.Every diagnostic trouble code (DTC) has a diagnostic route as prescribed by the manufacturer.These diagnostic routes are available through pay sources such as All Data online.If the simple things like plugs and wires doesnt fix the problem,then diagnostics are in order.Good luck.

Try changing your MAP SEnsor. I had the same problem on my acclaim

Aloha We have just replaced all of what you have replaced, plus water pump, fuel pump, pcv valve and 02 sensor. Took it to mechanic today we had misfire on 1,2,6,7. Mechanic said that the 99 dodge is known for bad computers, he checked ours and works great turns out that it was the coil. Ours was jumping 1/4 inch and had a orange/yellow spark. it is supposed to have a 1 inch spark and be blue. This has solved our problems after 527 dollars later.
Check the coil!

I found this; if it helps.
The injectors need to be cleaned, if an engine is experiencing any of the classic symptoms of dirty injectors, such as lean misfire, rough idle, hesitation and stumbling on light acceleration, a loss of power, and higher hydrocarbon (HC) and carbon monoxide (CO) emissions.
Lean misfire may also trigger a misfire code and turn on the Check Engine light on 1996 and newer vehicles with OBD II systems. The code often will be a P0300 random misfire code, or you may find one or more misfire codes for individual cylinders, depending on which injectors are most affected.

My 2001 Dakota now works fine, I took it to a good reliable shop after much frustration. The problem was the crank position sensor in combination with an bad oxygen sensor. This was a very unusual problem with no consistency therefore hard to diagnose. Crank sensor $190.00 cdn oxygen sensor $130.00 cdn $300.00 in troubshooting, repair and diagnostics. Repaired by Gerald at AutoPro in Corner Brook, Newfoundland. Thanks Gerald
