I have a new problem now which is annoying and i can't seem to get rid of it. It is a constant whistling sound which seems like its coming right out of the injectors. I changed the injectors along w/ the FPR (swapped them from my 92 RS), tightened all the throttle body screws and bolts and fuel lines, and the problem is still there. When i put my finger over the injector to stop the fuel from flowing, the whistling sound gets louder, so that's why i think its fuel related, and not vacuum related. Any ideas of what it might be? Thanks

I had a problem very similar to this. My problem was that the gasket between the TBI and the intake was cracked. I replaced the gasket and the problem was solved. I don't know if this is the same problem. I found it by squirting soapy water around the area it's coming from. When the wistling stops, that's the area that it's coming from. I don't know if this will help or if you have already tried it, but it's my only advice.

i noticed that strange whisling sound once i installed the K&N open element i think its the throddle body taking in more air that you may have not heard it when you had the snorkel set-up on the engine i never noticed it until i put the k&n on ... it's the K&N filter allowing more air to get to the engine the snorkel was more restrictive and it may have been quieter.....
