Ok I have a b18b1 that was idling at 3200 so I tightened the FITV and it dropped to 1500 so I cleaned the iacv didn't do a thing. Checked for vacuum leaks couldn't find any. The only code it's throwing is the o2 sensor #41. Also there is no air in the cooling system. Any ideas?

 

How did you check for vacuum leaks?

 

Brake cleaner around TB and IM

 

Also idle screw is tightened all the way. Anyone?

 

Adjust your idle screw correctly.. ill be nice, here you go

Ok hey man that didn't work. It still idles at 1500 warm, and of you barely touch the throttle it seems like it wants to drop to normal idle but them goes back up to 1500 is this a vaccum leak?

 

Also I put my finger over the two holes in the tb the top and bottom so it's not the FITV OR IACV is this a vacuum leak!? Please help

 

Really HT? Nothing?

 

You have a vaccum leak somewhere man. Check the nipple in the back of the intake-mani-fold, plug that. Ensure you don't have a leak on the PCV hose. Check your IAT sensor for leaks. Check your IAC mini gasket for leaks. Adjust your idle the proper way by unplugging your IAC, turning on your car. Setting it to roughly 450- 500rpms. Then plug your IAC, reset your battery, and start the car, it should chill near the proper RPM.

 

he basically just covered it all right there. adjust your distributor, maybe belts could be too tight idling problem is a bitch.

 

Give an update if it worked.

 

I believe I found my problem. Sprayed the tb again with brake clean and it stalled out. And I could feel the air it was sucking. I'm gonna change that and adjust the idle speed correctly and I'll update hopefully tmrw cause oem gasket is on order

 

I have same problem but can`t find why it looks like everything is correct and no vacuum leaks but it still idles 1000 1500 rpm-s

 

Its all fixed. It was the tb gasket!!
