hi im new to the forum, i have a 08 mustang gt that runs fine until it gets up to temp. it doesnt throw any codes. when it gets up to temp it runs ok at part throttle but if you give it more than 1/4 throttle or wot it bogs like crazy. not really sure what to do ive heard it could be coil packs?

How many miles are on the car and was any maintenance done to it recently?

Could be ignition related (spark plugs, coil packs), or gas related (bad gas or something) but I'm guessing the spark plugs.

it was my dads car it has been sitting for 8 months so im not sure about maintenance but i put fresh gas in it. has 131k on the clock,

Check fuel pressure.

i dont have a fuel pressure gauge, the car will rev all the way up just not if you give it full throttle its fine if you ease into it

fuel filter.

just curious, if it was fuel related why would it only do it when fully up to temp

My thought exactly.
Bogging is usually caused by a fuel delivery problem rather than an ignition misfire (unless it's on multiple cylinders). Since the car sat for so long either the gas has gone off, the fuel filter is clogged, or both.
Syphon off the old gas, refill with fresh gas, replace the fuel filter, and you should be good to go.
