car service question

[Boomtowner]

I have a '96 Explorer. In '98, I gave someone a jump and the light came on soon afterward.

The car ran fine, so I did the black electrical tape fix and it's been that way since. Have had other work done on it(brakes, hoses, belts etc.) and my mechanic never mentioned it.

I had some stalling and rough ride after an oil change, and I opened the hood and the oil guy checked the air filter and didn't seat the housing back properly so I reset it and no problems. Now I tell them not to check the air filter.
