So as we await delivery of new intake boots today hubbie took out the icv and cleaned it up and reinstalled it. He also started to clean the TB but when I press the throttle down from inside the TB plate doesn't open. When I turn the key to the second position(dashboard lights) the throttle plate opens about 1/4 inch but no more, even when I press on the throttle. He had read that as this is a drive by wire (2003 330i) he shouldnt push on the plate with his finger in order to open it. When it opened that tiny bit he sprayed TB cleaner in there. Should that plate open to the horizontal position when throttle is pressed inside the car or is this correct?
We swapped out the throttle pedal for the new one thinking maybe that was it but it made no difference We're thinking the a new TB is in our future.
