Hey guys I posted this topic on mustang forums but no body responded to my post. I have an 06 4.0 V6 automatic, totally stock but with dual GT take offs. The car has 79K miles, is extremely well maintained, and not beaten on to often. I am having an issue with my car stumbling during idle and have to be what sounds like backfire pops coming from the exhaust. Whenever you are sitting at a light with the car in drive, it will stumble and go from the normal 750 RPMs to about 500 RPMs then catch itself and go to normal. Then 5 seconds later it will do the same thing, and this process repeats over and over again every few seconds and feels like the car is going to stall. If you stand behind the car you can hear the car is running like shit. Its burbling and popping and sounds erratic. When you rev the car up and hold the revs at about 2 grand the car stumbles and shakes and the exhaust pops. The thing is It drives with no issues, at least that I can hear on the freeway and all. No loss of power, no nothing. The service engine soon light has never come on once, which I find weird. I just changed the oil last week with fully synth 5-30, ran some gum out injector cleaner through a tank of gas, and the car started doing this about a day after I did that service. Today I installed a new fuel filter, and filled up the tank with 87 octane from another gas station in case I got some bad gas. Nothing has changed at all. Right now I have the battery disconnected to see if it clears the issue but I highly doubt it will do anything. Does anybody have any ideas what the hell I can try to fix this car? The throttle body is spotless, I cleaned the maf not too long ago, about 25K on the spark plugs. What is wrong?
Here is a video I made of the car and how shitty it runs, I have a friend idling it at 2K. You can hear the burbles I am taking about and all.
