Hi guys my name is Ray and I need help with a problem with my 2005 mustang gt, I have been searching information but I have not found a solution, I hope you can help me!
my car turns normal, but after 15-20 minutes of driving if I get stopped at a traffic light or in traffic, the car makes a noise and loses power but does not turn off, no explosions were heard in muffler just the engine sounds like several cylinders will not work!
The TB is new from the site american muscle, new water pump also, on the board no warning lights! right now my car is in the shop but the mechanic can not find the reason for this failure! I hope you can help me!
Thank you

 

More than likely its the Throttle body. Put the stock on back on and see if that fixes it.

 

I change it because I thought that was the cause of the problem but not

 

Is the car overheating when this happens? Does the display say "Failsafe Engine Mode"?

 

Neither the display or the temperature gauge marks something different!!

 

sounds like it is missing ?

 

Which throttle body did you replace it with? If it was any other than the Ford Racing Stock Replacement, I imagine you'd need a tune to go with it.

Possibly was your original throttle body, just may have needed cleaning.

 

Most likely it's gonna be what everyone is saying, the throttle body. See if you can get an OBDII reading see if any codes are being thrown
