Question about Pontiac Grand Am
Most likely cause is the auto choke isnt coming off ,this is most likely due to a temperature sensor on the cylinder head somewhere but where exactly i have no practical experiance on this american model

It would help me diagnose your problem if you let me know what year and model the car is. If it is an older car I would say that the choke is sticking closed. If it is newer then it could be many different things. Such as the Mass Air Flow Sensor, Manifold Air Pressure Sensor, Cam Sensor, Knock Sensor, O2 Sensor. The list can go on and on. So please give me more details. Thanks!

I suggest check the fuel pressure also the screen in the tank could collapse after a period of driving and cause fuel flow problems. The trans, although unrelated sounds like it is going to be a problem also.
Also, this could be a problem with the ignition module (potentially either one or more of the coils, or the module itself). They can sometimes cause problems only after they heat up.
Several thnigs to check; to me it sounds like part of the problem could very well be DIS Module
Heat Soak. I would replace the entire DIS unit with a used one. Then I would check the coolant temp sensors, and make sure the fans are comming on and running properly. Overheating will cause power lose.
As for the transmission. You need to have the fluid flushed, and replaced. As well as the filter. Fluid that smells burnt or is discolored needs to be replaced.
Hope helps; keep us updated.
