I have a Dodge Grand caravan 2008 with 84,000 miles. It idle's good sometimes then when you go to step on it sometimes it'll spitting and sputtering no engine light than I'll try to use the resume on cruise control and it speeds up than it stops and doesn't go to the right speed. I gave it a tune up new plugs wire electric coil. Replace 2 transmission speed sensor and it work good for an hour than it started spitting and sputtering. It doesn't matter if the engine is hot or cold it does it. HELP

 

Could be the crank position sensor, ignition coil, fuel pressure from tank module, throttle position sensor... etc
I'd need to narrow it down by process of elimination,

Is your van running poorly all the time now or is it intermittant? And you say no CEL and no codes? Did you try to see if the 'key dance' will show any codes?
\-Set odometer to vehicle mileage, then without cranking the starter turn key [ON] [OFF] [ON] [OFF] [ON] and the codes should appear in the LED window one at a time until it reads "done"

Look them up google, and post them here. (both the number and the search results)
That is, if you have any stored...

 

I knew nothing about the key dance but ,I did the key dance the engine light flashed 10 times don't know what that means
The van idle's really good but once in a while it will idle a little rough just enough to get my attention.

 

The engine runs great but sometimes it spits and sputtering for a short time. Also it stops the cruise control from working, even tho the cruise control light is on
