I recently took the throttle body off and iacv an gave them a clean with a throttle body cleaner, i put it all back together.

But i accidentally knocked the throttle position sensor so the idle was bouncing up an down, I calibrated the tps back to standard 4.5v WOT 'wide open throttle' and .48v CT 'Closed throttle'

And now i start the car up it will idle fine, but as soon as i touch the throttle it will rev to 3k at idle or when the clutch is engaged,
the car drives normal when in gear an i just replaced the alternator belt today not sure if that changes anything.

Link To Video of what the car is doing - http://www.youtube.com/watch?v=eGLF08shzJQ&feature=player_embedded

btw the car is a eg5 with a jdm b16a

Any help would be much appreciated
Cheers

- Thu Jun 09, 2011 10:49 pm #258863 I don't have a fitv under the throttle body, I'm thinking that this could be the Intake air control valve, is there ways to test it to make sure its still working?

- Fri Jun 10, 2011 6:48 pm #258990 I was 3 seconds away from saying check for vacuum leaks.

The IACV has a figure 8 shaped o-ring that becomes brittle over time. Make sure you didn't crack the o-ring. My 1st Integra did the same thing for a little while. Replaced the o-ring and all was well.

Also, spray some carb cleaner around the IACV and TB to determine where the vacuum leak is.

I have found the problem, the throttle rotor with the spring attached is getting stuck at 3,000rpm whenever i touch the throttle, The spring is very loose an need to be tight like this one -

Thanks for the help guys:)
