A Protege5 5 speed popped up on CL a couple days ago for really cheap. I went and had a look at it today knowing it had some issues, it seems to smoke a bit when the engine is cold, and is throwing an O2 sensor code and PO300.
When I arrived I started it up and the engine ran just fine.. After idling for 5 minutes the Check Engine light was flashing and the car was running very rough. I pulled the plug wire from #3? cylinder, and it wasn't sparking at all. Pulled the injector plug for each cylinder on that coil and neither were firing. That coil was dead.
After idling roughly for 5 or 6 minutes, that coil came back online and the car was running perfect again. I'm thinking bad coil. Do you guys agree? It just seems a little odd to me that it would up and start firing again.
The car is cheap enough that I'm not too worried about these issues. Even if I have to rebuild the engine I will still come out ahead of blue book value. The car is in great shape.
As long as the car passes inspection without any issues I will buy it and bring it home next week. I will probably throw a coil in it real quick before I take the 90 mile trip home.
