ive had my 93 FZJ for about a year now. Since I got it I have noticed an intermittent idle issue. It idles pretty good in park at around 750 RPM. It does have a little "shake" to it. I was told it had aftermarket cams in it, but this is unconfirmed. I'm not sure that would make a difference anyway. It seems more like a miss honestly. When I'm driving the truck it has a bit of a dead spot in it that eventually goes away with more throttle/speed. When I come to a stop its a crapshoot. It might idle ok at 750, it might idle at 450 and shake pretty bad...or it could be somewhere in between. I've done general tune up items, removed the EGR and PAIR valve, cleaned the throttle body (which was missing two mounting bolts) and other maintenance items. I've noticed a raw fuel smells of late, so a vapor canister is on the way. Any ideas on where to start? I love driving this thing, but the idle issue gets pretty annoying. Thanks in advance!
