I have a 1999 Chrysler Sebring that I'm on the verge of giving up on. I have replaces all the spark plugs and the distributor on the car was recently put in but im still having a random misfire. Ive been told it could be because of the oxygen sensor and/or I need a new EGR or something like that. If you have any clue on what the issue is with this vehicle please help me out.

 

What codes is it displaying?
Gummed up fuel injectors won't have a specific code, but faulty O2 sensors probably will.
Consider:
Fuel injectors
Spark plug wires
Distributor (maybe you got a bad one)
