sputtering m111?

[Will_w202]

went on a road trip this weekend to the beach, the evening after I got back I (for whatever reason!) revved it to 3k while in park, not while driving, and held it there for a minute. It started rhythmically sputtering, chug-chug-chug-chug, but today it doesn't do it. Bad plug? Bad hole? Ignition? I'm beginning to think I own a real POS.

Hi Will,

I'm about 99% sure that I read in my manual that that's normal, i.e. when in park, there's a rev limiter of some sort that keeps the engine under 3,000 rpm.

[Will_w202]

Interesting! Hope you are correct.

Try again three ways, in park, in neutral, in gear, and see what happens.

What was the reason for revving it to 3 k rpm in park to begin with ?

Yeah, that's not healthy. Unloaded engines should not be revved hard. Take the car for a drive, run 'er to 6K through the gears and let us know the results. If it falters at 3-4K or so under load, I have a guess...

well I was showcasing my new stereo to a friend and using all it's ability, so I wanted to make sure I re-juiced the battery before turning it off.

And I know you will say that's unnecessary! It's just a hangup of mine I guess.

Anyway, zero driveability issues, but I tried it again yesterday and it didn't do it at 3k. So I dont know about that rev-limiter deal.

try 4k. I'm curious now.
