now...as i'm new with my mustang i have a few issues that come up at idle, and when accelerating

sometimes, not when i engage the clutch, but when i put it into gear, the car stalls.
why is this? it happens when car is cold, and even after driving for an hour

also, when accelerating i hear a high pitched whining sound....

i do have an opened throttle body. is that it?
don't wanna sound like an idiot or nothin but hey i'm new! i st

 

Maybe you got a supercharger you don't know about....lol....but what do you mean you have a opened throttle body do you mean no filter if so I suggest you put that back on you prolly just killed 5 years off your cars life

 

ahahha

 

If there is not tube from the throttle body to the filter...then it is safe to assume that youMass Air Sensor is floating in the air not reading anything...

That is if your can uses a MAF...I believe '89 and up have MAF

That would cause idle problems for sure

 

maybe he means that someone took a dremel to his throttle body

 

ahaha no.....it has a filter, no supercharger. but why would it stall when i put it in gear?

 

how many rpm's does your car idle at????

 

roughly 1000...but whenever i put it in any gear at a stand still, the car loses rpm's and then surges if it hasn't already stalled

 

are you getting a check engine light? maybe you should check for stored codes.
