So I bought a 2000dakota cc 3.9l. Did a tune up, plugs, wires,rotor cap and dis cap alone with oil filter , oil and air filter.Did some more reading and changed the map sensor as well.Was running okay with no codes .was driving and it just died and bucked a lot turned out to be an o2sensor changed it out with an ngk code gone .So I thought I was good.Now it still does it at red lights bogs down and when I give it gas to stop it from shuting offyhe peddel feels like it sticks. have to hit the brakes cause rpms stick for like ten sec.I'll be driving let go of the gas but the rpms stay as if I had cruse control on .if it does it at a red light I have to shut her off and turn her back on .that sloves the problem for a lil bit please help big blue .....thanks .......p.s she is all stock

 

02 sensor code came back.............WTF......
