I just bought a 1992 colt for my daughter. Of course it ran perfect at the dealer. it has 69800 miles, in other words the previous owner did not drive alot. After We got it home it began to run rough at idle and when cruising. smooths out when accelerating. Also does not do it all the time. sometime runs great and will runs great. I have replaced the plugs, cap and rotor, fuel filter, checked all connections. Next is the wires didn't rplace those. If that doesn't work will replace the Oxygen sensor........anyone have any other thoughts. I have a 2000 firebird that had a faulty coil it ran very similar to this, and will probably change the coil/distributor after the sensor if that doesn't fix the problem.

Excuse me here, but a car is a car not a person ? hence it is not " born " but made or fabricated, also it cannot sustain " injuries " ? you can name it whatever you want but that changes nothing, still a piece of metal.
