S13 Idle issues ka24de

[XxNickxX]

So a few days ago i switched out my water pump because it was leaking throught the weep hole and while i was doing that i also decided to replace all 3 off my drive belts but now that i did that im having some idiling issues, the car drives fine but when im coasting it'll start to idle down until it stalls out :confused:
Would appreciate any help... I was thinking that it might have to do with The ignition timing but im not sure.

retrace what u did. it might just me a loose vacuum hose or and unplug sensor.

This is infamous on most 240sx. I can't explain why either. On my old 240sx, if I shift into neutral while coming to a stop, sometimes it would totally die and stall out. On my current 240sx, I don't seem to have a problem with the idle. On my old 240sx, to combat the low idle/stutter, I would turn my AC on all the time raising my idle a bit and blip the throttle.


Its either related to, vaccum leak somewhere or some people have said dirty IACV.

I had that problem before and was able to found out it was the power brake booster hoose. Exact same issues and same "work arounds" too. Stupid enough, hole/crack was too small to tell until I bend it really hard.

The other idle issue I was able to resolve, crank sensor & distributor was bad.
