I removed the throttle body today to give it a good clean out.
I noticed when the throttle is fully closed I can see some of a gap between the butterfly valve and the throttle body. Especially when holding it up to the sky I can see some daylight between the flap and body. Is this normal?
I have high idle problems and im wondering if the extra air which can sneak thru here is causing the slightly higher idle?
Does this make sense? I hope someone can help out, thanks
