Need Help Finding Source of the Problem
Okay, so I have done a lot to try and figure out an issue I am having with my v6 05 Mustang and nothing has gave me a solution or worked. When turning on the car, at idle there is what sounds to be air leaking some where in the engine. It sounds much like "tis..tis..tis..tis..tis" not sure how to describe it other than that. I have changed the plugs, wires, coil pack, tps, air filter, fuel filter and even had a full throttle body cleaning done. Sense it has started making this noise my car has been acting up in a couple of ways. If standing by the exhaust it sounds like the air flow just stops for a second in the exhaust and then goes, you can even feel the air flow stopping and going. Problems that occur while driving is that the car will rumble occasionally, sometimes when pressing the gas pedal nothing will go through and if I hold down the pedal sometimes the car will end up reving up and working for a little bit, or it will just stall at times. Its hit or miss when it wants to drive places, sometimes I can drive it 30 minutes no issues, sometimes I turn it on and 5 minutes down the road it stops working.
I have done research on forums I have used the scanner to pull codes from the computer in the car sense my engine light is on but no codes has ever came up, I have taken it too three different mechanics they are unsure of the issue, so I figured I would post a thread and pray that someone can help on the internet. Thank you in advanced any help or ideas would be appreciated I would love to be able to get this car working even though it is a v6 :p It is my first car and planned to keep it for as long as I can.
P.S. My serpentine belt does need to be changed, but I do not believe it would do this much damage as it is not completely trash. My next step was to change the harmonic balance as I have seen similar problems to what I am describing and that ended up being the solution but figured I would try and get some tips first.
