My '96 318ti wasn't running correctly. Difficulty starting once the temps dropped and it would run rough the first few minutes. Yesterday, I was warming it up and came back and it was off; I couldn't keep it running at idle. For a quick fix, I raised the idle, which enabled me to get around for the rest of the day. At some point yesterday, my check engine light went on. Anyway, my instict was the plugs, which I changed today (they're the originals w/70k on them), along with the ignition wires and an oil change. Seems to have done the trick -- car starts up fine cold and I turned the idle back down; however, CHECK ENGINE light is still on.
Does this mean I did not fix the problem OR does the CHECK ENGINE light need to be reset (i.e., once it's triggered, it will stay on until reset by the dealer)?
Thanks, and Merry Christmas everyone.
