Welcome! I don't have a GP as new as yours, the base model is 3800 NA? No heat is typical of air in the system. Gas could be a leaky fuel injector. Are you mechanically inclined?
First off welcome to the forum!!!!! Yeah it's an NA I have the same model. It's a great car gets good gas handles decently and is ok for speed. Have fun lots of easy mods to get these cars going
