i got a 95 dodge spirit 4cyl ive bought about a year back and up untill recently ran smooth.Anyway it runs rough on idle cold or warm but driving it its fine.Plugs and wires are close to a year old but look like new.i checked the plug gaps and they were pretty well dead on.i checked the vacuum hoses and they also look great.The car also starts fine any ideas what it could be thanks
You are going to have to connect a scan tool to monitor the sensor inputs and outputs. A faulty map sensor or coolant temp sensor could be the problem

try a good valve cleaner or also try to replace the fuel filter i have a 91 dodge caravan with a l4 2.5 that i just tore down and rebuilt my self and it was running rough bfor and i found out that when i took the head off it was all deposeted up on the valves so i cleaned em all up and rebuilt the springs and boot seals in the head and now it runs like brand new my other car is a 90 grand voyager that had a 3.3 liter in it and i took out the engine and changed the wireing under the hood and put in a 2.5 liter in it and it was running rough too so i dumped in lucast oil treatment and now it runs fine and smooth so try a good valve cleaner and also try to replace the fuel filter
