97 caravan running very rough for first 10-15 minutes

From : g

Q: 3.0 liter changed plugs normal color wires cap & rotor needed to have it done anyway it runs very rough no blue or black smoke until car has gone 15-20 miles. it evens out after its been run for 10-15 minutes makeno difference if its in-town driving or freeway. we can let it idle for 20 minutes and it will run fine as well after that.... map sensor im looking for ideas here... thanks .

my 98 dakota had the same noise at 66k miles.. rear end shot and the front wheel bearings were done.. get ready for sticker shock the front hubs were 180$ each part only rear end was another $500.. dodge tough.. goodluck .
