Hey guys posting this here also because of traffic... I was wondering if anyone knows what that inverted (upside down) screw with the spring on it is...? It seems to adjust some sort of plunger type of valve... Its located directly above the oil filter on the throttle body. Of course on the driver side . I can see a coolant line that runs into it so I'm guessing it has to do with coolant flow...but not sure. Is this screw adjustable at all..? Or does it effect the performance of my 3rd Gen if its been tampered with...? Because I accidently adjusted it ...thinking it was the idel adjustment.....give me a break it was when I first got the car and didn't know any better. Basically what is its function and how do u adjust it ..? ....if u can that is. I'm worried about it hindering the cars performance. I would greatly appreciate any info anyone might have...Thanx Tony
