Got a 2002 Toyota Sienna, about 60000 miles. Once in a while, I would start my van and it would start off and idle very low and the engine would eventually stall. I'd try this over and over until it eventually starts off and idle normally. Any idea what this may be?

First, check for vacuum leaks, if ok, check the mass air flow sensor. We have replaced many on that car. Also Scan your PCM for trouble codes.

Suggested Repair

Check for vacuum leaks and scan the PCM for trouble codes. If no leaks are found, inspect the mass air flow sensor and the idle air control valve, which can stick and cause a very low idle and stalling.

A 2002 Toyota Sienna with about 60,000 miles occasionally starts with a very low idle and then stalls, but eventually starts and idles normally after repeated attempts.

Another expert notes that a sticking idle air control valve can cause this problem, and that suggestion was confirmed as a known issue.
