Low idle!?

[89 e30]

I looked through a lot of threats couldn't find anything. I have a e30 m20b25 and idels at around 500rpm and shaking like crazy. Acceleration seems kinda slow too. I cleaned the icv replaced maf, vacuum hoses, intake boot, coolant temperature sensor. I havnt replaced the o2 sensor yet and my crankcase breether hose is broken. Valves are also ticking, I don't know if that has to do anything with the idle tho.
Anybody has any ideas???

make sure all of your injectors are firing. Take a long screw driver, put your ear at the handle and touch each injector with the tip. You should hear clicking.

What happens when you 'blip' the throttle?

Is your Check engine light on?

If you disconnect the icv connector while the enigne is running, does the rpm's shoot up?

try covering the crankcase breather hose with tape or your finger if its small enough and

see if it does it.

The problem was the breather hose! Thanks for the replies
