little help with the rpm

[litoasianbboi]

hey guys can anyone tell me wats wrong with my 95 zenki. everytime i start the engine the rpm go up then it go really low, almost to 0 and the engine is barely hanging then it goes back up to normal. also when i step on the gas and let go the rpm goes up and down a few time before it stable.

Try cleaning out your idle control valve with some carb cleaner. This should halp. You can adjust the idle via this aicv or in extreme case, the throttle cable tension via throttle body screw.

yea, mine does this too. Does it also happen when you brake really hard?

vacuum leak, vacuum hose to iacv? timing? make sure it's all in working order.
