l have a 2004 Sebring. It has 70K miles. About 5k miles ago the car would stutter and feel like there was a lack of take off power. It would really act up when the AC was on and l was running idle.
Well, l changed the spark plugs and the issue went away ......until this week. It is not as serious as before but l am afraid that it will come back. Is there anything else l can try myself before taking it to the shop to get bent over?
It is a 4 cylinder 4 door sedan again 70k miles.

Should of purchased a more reliable vehicle. There must be some type of problem with your fuel pump.

maybe your plug wires need replacing, or you could just have a vacuum leak check your vacuum lines, also your ignition coil could be bad. have an honest qualified mechanic check these things out.

Its your catallic converted stopped up..Change it out for about $150.

where did you get your spark plugs?
you did not put Bosch or anything other than the stock plugs that can make your car run funny
did you check the gap before you put them in.
i would change the plug wires and do a fuel system tune up.
