I installed a fmic a few weeks ago and took on one long test drive. Noticing the trailer hitching was worse and researched doing a bypass valve.
I havnt driven it since, been waiting on getting a new radiator.
I had a Bosch bypass valve I bought about 10 years ago from forced four. So I bought the needed hoses and started plumbing it in.
I have it on the throttle body side and hooked up. But I have it unhooked from the Turbo inlet. And the inlet hose to the Turbo is block off.
I had to move the car out of the garage yesterday and it wouldn't stay running.
The valve is "bypassing" at idle so I have an unmetered air leak right now. I unhooked the vac line to the bypass valve and was able to move it.
Question is: is this normal? It bypasses at idle, or high vacuum conditions?
