I have a 2002 Taurus that I had let my friends use for the past year. Now that I have it back I notice 2 things. Not sure if they are related.
Check engine light is on. (it’s just a picture of an engine which I assume means check engine).
The battery light is on.
A parts store hooked up a battery tester and it seemed okay. He said he would also test the alternator but he didn’t really hook any cables up to the alternator. He left it connected to the battery. I’m guessing he just changed the setting on the meter (analog).
Both were done with the car running, nothing running. And then with the a/c on. The load dropped some but still seemed normal.
Is it possible that the battery my friend put in it is possibly too small? The battery is new (May 2012). The car seems to be running fine except I noticed some “sputtering” (for lack of a better term) when I was driving it today with the cruise control on. It isn’t constant, just something that happened a couple of times. Also I noticed the engine try to jump out of the car when it was parked and testing the battery and I gunned it. I’m guessing a broken motor mount.
I’m going to take it to a shop on my next payday but just was wondering if anyone here might have a clue because I obviously don’t.
