I have been having a rough idle, its not in a ram, but i thought that i would get the best answer in this section. Its a 1995 Chrysler LHS. It has a very rough idle and when you come to a stop it wants to stall. I have checked the plugs, wires, coil, all fine, they were all replaced a year or so ago. This car has 157,xxx miles on it, the cat or the fuel pump has never been replaced. This rough idle just happened yesterday, really rough, it feels like its missing. Before it developed a little vibration at idle but now it sounds like it wants to stall, kinda sounds like its got a big cam in it or something. Could it be the cat or the fuel pump???

Thanks

 

sounds like a plugged cat or bad plug wire, might want to repost this in the general tech forum, you will get more hits

 

is the check engine light on if so could be a bad o2 sensor
