Hey yall,
I recently bought a Manual 05 GT with 150k miles and after a few months of ownership the car runs perfect when cold or driven for less than 10 minutes but I'm having a rough idle when the car gets warm. This only happens when stopped or in neutral and the rpms drop to around 500 then go up to 700-750ish and continues to shake the car almost in a cammed fashion with a notable tick/knock noise. If I don't rev to around 2k rpms before moving it does a sort of bucking/underpowered...
