Have new battery, complete tune-up, all oils and filters changed, fuel pump is good, have replaced crank and cam sensors, map sensor. have done everything i can think of to resolve this problem. vac pressure is fine. car starts and runs great every other day but i need it to start every day. anybody else having this problem? does anyone know what's wrong with it? i also had engine compression checked and that's fine also. i'm running out of ideas.
