Hey guys I have a question.I was tinkering around with my '86 MR2 (4AGE) today and I accedently broke a vacuum line tab going to a switch. According to my 'Haynes' maunal (page 121) it is an 'Fuel pressure up vacuum switching valve' Could someone tell me what that does? What might happen to my car if I were to bypass it? I get the idea that it is an air conditioning thing. I don't care about air conditioning. I do care if my car overheats or has some other mechanical problem though. Please help if you can<br>thanks<br>-Mainsoda
