99 stang idle probelm skipping
Any help would be great! My 99 mustangs idle jumps up and down and even sometimes shut off. It is also skipping and if you rev it up you can hear a popping like sound. my plugs look good and the coils where all replaced about 1 1/2 yrs ago. I have acess to a Determinator scan system but dont know how to use it :( My abs light stays on and my coolant light is on most of the time also. Levels are fine
