Hi. Im new here. so hello! My name is Chris
im getting a vacuum leak where the air box eventually connects onto the throttle body. I think its a vacuum leak because I am able to coast at 20mph for about 6 or so seconds without my foot on the throttle and the revs stay raised a bit ( its like my foot is gently on the gas) Im also getting some surging after I first take off and then let my foot off the gas.
Anyway, Iv sprayed carb cleaner at this location and can tell a big difference in engine speed for sure. The thumbscrew holding the intake onto the throttle body was lost a long time ago. For some reason I cant grab any threads on the stud that the thumb screw goes onto with a normal bolt? The studs threads don't start until about a quarter inch down, if that makes any sense? I was able to loosen the actual stud a bit to get a bolt on and tighten it down a bit but im sure that is not good at all.
I think my main issue is the a plastic seal/gasket inside the air intake that sits on top of the throttle body and goes over/onto the throttle body itself. Its cracked into two pieces and old. I am sure this is letting in air causing my issues. I can not find the name of this seal or part number that I need to replace. Iv looked everywhere online and cant find it either. Is there any other way to seal this part of the intake otherwise? Remember, I'm not talking about the throttle body gasket. I'm talking above that, at the very top of the throttle body where plastic and metal meet. Its almost like there shouldn't even be one there, but it is?
I'm sorry if that doesn't make much sense. Its a hard issue to describe. I'm not the smartest at identifying parts either.
Here is a picture of the place I'm talking about. The red line is where the gasket is and my leak is. Any advice would be greatly help!
