driving home the other day from work, after i came to a light, i felt the engine studder like crazy and the rpms droped like CRAZY! looked at it and it had drop all the way down to like 100! is that normal or is that just me? the only code that i have is, for P1133. still havent gotten a chance to do the spacer thingy yet, but that woundnt effect the idle would it? i guess i better hop on it and get it done asap!

Silly question but does that include a misfire at all? Mine just stalls below 200rpm :/

not that i know of? theres no codes coming up for misfire, just changed out the plugs and wires not to long ago. its drop all the way down and then jumps right back up. well im going to do the spacer thingy tom. if that helps i hope?!

Just FYI I wonder how you even know you went down to 100 rpm since the tachometer doesn't even have tick marks between 0 and 500 rpm :)

Yes, that first line on your tachometer indicates 500 rpm, there are no minor tick marks between 0 and 500 like there are between 500 and 1000. I would be impressed if anyone's boxer motor ran for more than 5 revolutions at 100 or even 200 rpm... think of how slow that would be, it's like 2 revolutions every second - steam engine, much?
