ka24de Idle problems help

[s13coupe92]

my 92s ka24de is idles very badly now. It flexuates between 400-1300 rpms at idle. when i drive it dies when i press it the clutch and the rpms drop too low. ive read alot of similar problems but im not really sure of what to actually do. what should i be checking for first?

Bump, I really need some help. I don't want to take it to the shop if its something I can do myself. Btw my car is also shaking like hell now at anywhere from 300-1500rpms

Vac leak, clogged iacv or maybe bad tps. It can be so many different things on tge s chassis. What was your last mod stuff like that. No ones gonna be able to give you the miracle answer your looking for though. Do work.

Have you checked that all injectors are working?

spark plug wires good still? put new plugs in it, check fuel pressure, check injector pulse, IACV clean/good? hows the TPS? Check for vaccuum leaks.


and if youve done all of that and come up with the problem still, then give me the car and sit in a corner til you learned your lesson for being incompetent

k so my idle isnt dropping at all anymore, it just sits at 1000-1200rpms sometimes. Kinda narrowing down the problems. my injectors are good, fuel filters changed, sprak plugs look good, same with wires. throttle body was cleaned nice and good. anyone have any hint to what it could be? i have my iacv and some valves to check?
