hi i have a 2001 jimny a few months ago i was driving back from town and my revs started to shutter (over 3500rpm) done a bit of research on here apparently it seams like its a common problem with the crank or cam sensor. all well and good, as i was towing my boat home (fairly solid boat bout 1000kgs) at 80km doing just over 3000rpm its done it again but the check engine light came on and didnt wanna idle. got the boat and car home eventually i have got one of the sensors (crank angle sensor) just have to change it now...

so is the is sensor behind the alternator?? and went i take it out will any oil or liquids come out??
just don't wanna go in there rippin plugs out that i don't know what they are!
thanks
