Drop in RPM

[dblmikeusa1]

Here is an interesting situation... I took a road trip 160 miles away from my home all highway. Upon stopping at my first light the car acted like it wanted to die. The RPM dropped from idle (750 ish) to just below 500 and sputterd, doing this three times before I gave it gas. It then stopped on its own and has not done it since. Keep in mind when I bought the car, that 160 miles put me around 800 miles I put on the car. The dealer said the car sat for a while, long enough to drain the battery, also he had to put gas in the car when I picked it up. My first guess was bad or cheap gas. I have been putting 89 octane in since buying the car. Anyone heard of this issue before?

Unfortunately there were no electrical malfunction indications. Usually a battery light or charge light will come on if the alternator is dying.

89????

dude, it's a bimmer, give it 91...

but it sounds like maybe it was the alternator, who knows

800 miles on it? take it to the dealer, make him take a look, if he doesn't find anything don't let it keep you up at night, it was probably nothing.

Not always true, i had about three alternators die without a warning light. i heard the spool make more noise than it should, and the lights dim alot, but no warning light. that only happens when the battery dies.
