Hi guys, New here.
My girlfriend's 2000 FOCUS runs fine most of the time and a random it idles badly and has sometimes stalled. I did a tune up which it needed but It still acts up randomly. My guess is the engine computer malfunctions when this happens, No check engine light comes on though, the light that does come on when this happens is the little red light right above the HAZARD triangle switch, Is this some anti-Theft system glitch?
its the base 4cyl engine. any help is appreciated
