Engine skip at slow speeds and low idle - 2002 kawasaki ZX-7R

Not sure what you mean here. Is the engine idling at too low of a speed or do you wish to adjust the idle so it idles at a lower speed because it's running too fast? If it's the latter, the engine control computer has complete control over the base idle speed and it is not adjustable at all. However, if it IS idling too fast then this means that the engine control computer has reached the limit of what it can do and the still too high of idle speed is being caused by a mechanical cause, usually a vacuum leak. I don't believe I've come across a 4200 that idles too slow but I've seen multiple vacuum hose leaks that have caused too high of idle speeds. Hope this helps.

skipped filters?
hiccup.s can be lots of things,
so tell when the hicup ,er misfire happens
hot or cold engine. ? or both.
at any speed. , only fast right foot?, or only wide open throttle?
only on hills. ?
so far , no miss at idle or slow speed.

if it does not need a tuneup, then I would say to check the coolant tempurature sensor. if bad it will result in. poor cold idle, stalling, rich mixture and ******** timing, slow idle speed, cold hesitation, stumble, poor fuel milage. good-day! if need be. change plugs and wires first ! this could also be your problem.

CHECK IDLE SPEED SHOULD BE 650 - 850 RPM. IF IDLE TOO LOW AC WILL PUT DRAG SLOW DOWN ENGINE CAUSING ENGINE TO STALL IF IDLE SPEED IS TOO LOW.

Most auto parts stores will scan the engine codes free or allow you to use theirs on site. Scan the code and post it back here for additional help.

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

the idle speed is controlled through the on board fuel injection control module (known as the PCM), even if u raise the idle at the throttle body the computer will slow it back down, however there is a problem that causes slow idle, do the following procedure to correct the slow idle issue, follow it exactly.

the idle speed is computer controlled and not adjustable, slow idle is caused by a dirty intake, do the following.

When you press the clutch the engine control computer senses the clutch is in and adjusts the idle speed, maybe the idle speed control motor is dirty and sticks, this will almost feel like a skip or miss, do you have any trouble codes?
