i have 94 intrepid 3.3L, i gotta fully warm up my car to the third temperature gage bar, so that means warm it up for like 30-40 minutes. if i don't warm it up that much, it'll die in the middle of the road and i won't be able to start the car till it is fully cooled down. but if i do warm it up, it runs fine for the most part. now i went and got it checked, no codes. then i changed all the spark plugs, new wires, new air filter, new fuel filter, new battery and nothing seems to be working. can anyone help? maybe it's a sensor problem? thanks in advance.
