1999 Honda Civic 4 cyl Front Wheel Drive Manual

I did not start the car for two weeks, when I went to start it the battery was dead. Jumped it left it running to charge battery it overheated and cracked the radiator but the problem is misfiring on cyl. 2 3 and 4. Autozone hooked it up to a computer and told me that. But everyonce in a while it will run fine. I was in the hospital for two weeks but it ran fine before I went in.

Engine running rough or misfiring can be cause by the following:

1. Defective spark plug
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
11. Idle air control valve.
