Hello, on my 2000 GT 4.6 5spd, I am having symptoms of a vacuum leak. Idle is at 1050 rpm, and another odd symptom: when I tap the throttle even the slightest it will rev up to about 1500 and slowly come back down, almost like its sticking. Ive had these symptoms for many months after the...

I have a 2002 Mustang GT and it is making an extremely loud high pitched noise noise near the intake manifold. I am throwing the following codes P1506, P0171, P0174, P0316, P0307, and sometimes P0303 and P0300 comes and goes. I thought it was the IAC valve so I replaced it but nothing. Then I...

Hey everyone, My 1965 mustang 200 6 cyl has a vacuum leak somewhere. The vacuum lines are all hard lines and there aren't any extra ports to hook up a vacuum gauge. What is the best wait to hook up a vacuum gauge? Also, would anyone suggest converting the hard lines into hoses for easy...

My car is bone stock minus the flowmaster mufflers. I have changed the IAC twice since January. It recently received a new TPS. I have taken the TB off and cleaned it out. I heard that the throttle body cleaner is bad for it, so I got some silicone sealant and re-coated the inside. There is no...

I picked up a 1997 Mustang in really nice shape for the money (I'm a mostly broke college student so I took what I could get) last week. It does have some issues with the driver's side power accessories, though, and I'd appreciate some advice. First off, the power locks. Passenger side...

So, here's my situation. After 2 years I finally had the transmission rebuilt in my 1998 Mustang GT. Before I took it to the shop I tried to start it with no avail. Come to find out it was the fuel pump. When replacing the fuel pump I noticed the grommet that is on the fuel tank which the...
