I've got a 98 jdm b18b with a act stage 1 clutch....some times when I'm at a stop and I press on the clutch my rmps will drop down to 300 and the engine will knock a bit but does not want to stall??? It's more frequent when I'm up hill a bit!!!

Help ????

pushing the clutch in at a idle should have no effect at all, try cleaning your throttle body, iacv etc. with some carb cleaner

I have cleaned the throttle body and it had no effect...could my Iacv be no good or on it's way there cause when I ride for a long time and come the a stop, my idle will act up and take about 3 tries (fluctuates) to get down to 700 or so!

Could also be a small leak in the MAP vac line..
