Vacuum leak ford f150

Vacuum leak at rear of intake. Thread Tools. Ive got the PO and codes so I ran a smoke test and have it coming from left rear of intake, Ive tried to use a mirror and flashlight but still cant locate it exactly because of stuff in the way, is there anything else at that location that would leak? I dont want to remove the intake of course if thats not the problem. View Public Profile. Find all posts by dallasf Received 77 Likes on 65 Posts.

Mine is gray in color and doesn't seem to have the gap. At like rpm or so.

Truck began to misfire, sputter while driving, idle really rough, loss hp. I replaced the coil, problem solved. Loss hp, shaking, idle rough, sputtering when I drive. So I go back to auto zone today to hook up the tester again. He said it read. He told me I have a vacuum leak, not a bad coil. Do you.

Thread Tools. Does anyone have a picture of there set up or know? Also getting horrible mpg about 10 mpg hopefully fixing the vacuum will help. Under heavily acceleration vents will switch to defrost as well. Picture attached of the house not connected coming off of the Resevior. View Public Profile. Find all posts by Auscal.

Joined May 4, Hello, An engine can run lean for several reasons and vacuum leak is one of the main causes. Do not use Seafoam directly into the intake manifold on these engines! However, it can cause a lot of trouble when it goes wrong. And idling while sitting in park just doesn't seem quite right either. Date code is It's just every What is yours at warm? Advanced Search.

You can also use crab cleaner to check for vacuum leak form the intake manifold. Warm idle on these trucks should be around rpm. Pretty sure the booster is fed off that line now. Truck is running while driving down the road after it had a KAM reset and idle relearn. Was this answer. Engine vacuum is a large factor in the equation of the fuel management system which is determined by the engine computer. Maybe a KAM reset would be a good idea as well? Maybe before it was higher with a vacuum leak, so perhaps you were used to that? So first step would be to do a thorough inspection of the vacuum hoses under the hood. Peppy, no bogging or hesitating. Most are listed for 2. Have you found anything? In this article, we will tackle the IWE problem, including the diagnosis and fixes. Fairly new to me f 5.
