1992 Dodge Colt runs rough
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.

runs rough when hot
to add to my last note I have dicovered that it only runs rough after it is warmed up, like after a run down the freeway. It is cold outside the thing i purring like a kitten.

Mass air flow sensor one side tests zero ohms
Still trying to figure out why 92 dodge colt runs bad. see previous thread.
I took the caps off of the sensors on the side of the unit (Mass Air Flow Sensor) and tested them with an OHM meter. One side measured .02999 ohms and the other teated zero. Is this correct? Shouldn't both sides measure?
The car misses when its hot. gave a full tuneup changed the oxygen sensor. cleaned mass air flow. car ran ok but would not idle. turned idle up and is running ok. Doesn't run bad all the time but when ti is running bad it is always when its warmed up.
