For all you 2.0 d-jet folks....
Look at your throttle body plate (the valve that closes over the TB opening). Does your valve have NO hole in it, one small hole, or does it have a nut and bolt in the hole? See three samples below. The third photo doesn't show the small hole plugged, but you get the idea. It is like the second with a nut and bolt plugging up the hole. Bonus question: What purpose does the hole serve and why is it closed on some TB's? (IMG:style_emoticons/default/beer3.gif) Thanks, Len PHOTO 1 NO HOLE:  PHOTO 2 SMALL HOLE:  PHOTO 3 HOLE PLUGGED - THIS PHOTO DOESN'T SHOW IT, BUT JUST IMAGINE THE HOLE IN PHOTO 2 IS PLUGGED WITH A SMALL BOLT AND NUT.  |

They came both ways. I asked the same question a few years back.

QUOTE(76-914 @ Feb 24 2015, 10:00 AM)  They came both ways. I asked the same question a few years back. Did you ever get an answer? They came both ways, but we don't know why. Interesting. Theories? 1) I know my car was a CA car - but I don't know if that's the original TB or not. Could it have something to do with the car having additional emissions requirements? 2) My car also had A/C.... but that was dealer / owner installed, so it is doubtful that has much to do with it. I was thinking the compressor added some additional load on the motor (especially when engaged) and perhaps they needed the additional idle so it wouldn't stall. That makes little to no sense though. I have nothing else. It would be nice to know though. They didn't come that way for no reason. (IMG:style_emoticons/default/WTF.gif) |
