Question about 2001 Ford Focus
Check engine light is on, when stopped and running the engine sporadically cuts out and revs back up unless its in motion. If left idling the engine eventually cuts out. There is also a black residue developing on the battery. What do i do to fix it?
Since your CEL (Check Engine Light) is on you will first of all need to have the ECM trouble code read by a OBD II scanner to determine the exact cause of the problem first before throwing any money and parts at it.
If you can drive it to your local AutoZone the can usually read your codes with a scanner for no charge.
The black residue on your battery could be just corrosion on the battery terminals. Open up a can of Coke and pour it on the battery, the Coke will eat the acid.
