I have had any problems with the throttle body. Also the pedal position sensor. Very popular problem.

Harnice to throttle body is needing replacement I'm told. Anyone else.

Ford Mustang 2011 3.7 letter 450000 miles
Seems this is making the car go into safe mode and making car need to be restarted well driving this is bad. Ford wants $160 for the replacement. Thinking scrap yard and perhaps I could save me some cash. Spent under 3500 so far for car and repairs. Seems lots of little issues. But I'm able to do most myself.
Anyone else out there got a rustang there trying to get to a million ?

Seems a bit extreme why are they saying it needs replacing? If it has been melted just find the damaged area and repair it. I see no need to replace the harness without a legitimate reasoning to do so.

Hard shifting over 3000 rpm

Ford Mustang 2003 3.8L automatic 292000 miles
I got this car semi recently as it was in decent condition and $500, when I have to give it more throttle to pull out into traffic and the vehicle gets more than 3000 rpm and it shifts the car squeals and one large shake as it's shifting, I took it to a shop and they told me it was the transmission mount as the rubber had deteriorated but even after replacement it doesn't do it as bad but it's still there. Is it time for a new transmission?

Same problem going over 3k rpm when driving, from a stop and accelerating over 3000 rpm car wouldn't shake... blown the head gasket, cylinder 3 and all the engine, had to get a new engine and still make it...

Getting up to speed the car will shift to 2nd and then keeping the acceleration up, it wont shift to 3rd unless I let off the accelerator, then it will go into 3rd, and then it flashes the engine light and will run like shit for a little bit, until the light goes off and will be back to normal, until I kick it down again.
