I've got the same issue with an 06 Jimny. Changed crank position sensor, MAF sensor, battery, spark plugs and leads, throttle body cleaned as clogged. Also Cataclean added to fuel tank and taken for long run. No EMS lights and diagnostics not showing fault codes. Am at a loss and it's getting worse. Was intermittent, now drops revs to around 400rpm EVERY time I stop. Also hesitates on acceleration but intermittently. Starts up ok but messes around having warmed up or after stopping and cooled down for a while. HELP PLEASE!
To check for a leak, carefully spray a bit of easy start around suspected leaking pipe. If revs pick up then check for splits
