Any ideas what this noise could be @ 4 seconds in the video ? The earlier noise is the e brake https://youtu.be/4Vrqur9y-7M
It only happens when the engine is cold(summer 80 degrees+ and winter)
It happens for about 1-2 seconds after it starts up.
When the engine has been running , it will not do it on the re-start.
2008 GT 5 speed 103k miles
These changes have not made any difference:
New SR performance throttle body
New K&N cold air Intake
New Ford performance axle back
Stock tune, Bama tune, 91 octane , 93 race octane, happens on any tune.
New spark plugs
Stock exhaust manifold, cats, hpipe.
Oil level is good 1/2's up the low/high range.
Any help would be appreciated!
I was banging around on the cats with my hand but did not really hear anything.
Also i notice a little hesitation when going through 1st and second gear when its cold.
I have a tuner datalog if that helps.
