My B16a at a stop idles from 1000 to around 200 RPM. When it gets close the 200 RPM it feels like the car is going to stall but it doesn't, it just shakes my car like crazy like it is stalling. I changed the injectors, spark plug wires and spark plugs and it helped a little, but still idles to low.

 

Check out your throttle cable and TPS

 

oh yea checked those and replaced both, still the same problem

 

first off... do you know how to adjust the idle? because it sounds to me like its just set too low.

 

+1. the little screw head on the intake manny next to the vac line. adjust while the car is at idle

 

Yea I know that, but it still idles too low at times

 

dude i had this same exact problem on my dohc zc... sometimes it would idle perfect sometimes it would act up and idle low. i replaced all of my vaccum lines and that fixed it. i had a leak in one of them. cant remember which one. just replace them all let us know if this fixes it!!!! Also.. i dont know if this would help at all... I tightened my alternator belt at the same time.. maybe just a coincidence but thought that I would note that as well

Is it possible because now sometimes it is idling at like 100 that the car would shut off?

 

i idle about 200 too, but thats when i dont have a vacum leak.

does anyone have any bright ideas to find a vacum leak easier?

its a jdm b16a

sorry to thread jack

 

no prob

 

i have the same exact problem. Let me know what fixes it

 

It sounds like the Idle air controle valve (IAC) isn't working properly , it could be a bad valve or The cooling system is low on coolent . If the CPU is reading the coolent at the wrong temp I may foul the signal to the IAC of the coolent temp sensor is bad. Check the coolent first

He may be right.
First of all, DON'T MESS WITH THE THROTTLE CABLE just yet!
It's a band-aid solution, if it's something else than you just mess it up even more by adjusting the throttle
Check your oil. If it's some what chocolate-milk, cremy like then it is the head gasket for sure.
Otherwise, it can be bad dizzy
I never had this problem myself so i can't tell you what's up right off the bat but you should keep trying these suggestions..

 

Brand New Mobil 1 oil with a flushed radiator and new coolant

 

clean the IACV.

i had a vacuum leak on my car. Just changed the entire vacuum system with sillicon hoses. Never had a problem since. :D

 

fix the idle. It wasn't sucking in enough air and my timing was off
