    I've got an 02 Tacoma 3.4 and yesterday it threw a check engine light as I started it up, but then ran fine for the 5 mile drive home. My brother disconnected the battery (I wish he wouldn't have) for the night and now the check engine light is gone.

    When I start it up, it has a very rough idle, doesn't rev up to the typical 1500rpm cold start, stays around 1000 rpm then down to 800/750, and then the engine begins chugging and seems to misfire, eventually "bogging" down and out. Any throttle and it immediately bogs/dies out.

    No recent work, no recent problems, just started out of the blue on startup yesterday. I don't have a code I can read since the light is now gone. Any advice on what this may be?

    Here are two videos... One just idle and one idle w/ revving.
