2000 Volkswagen Jetta GL Sedan 4D

Car runs need work tho. I just put a new head gasket spark plugs and coil packs new oil and coolant. I dont have time to work on it any longer it starts and runs rough has sat for a while so pry has bad gas is what I am thinking what it smells like anyway. It is straight pipes but I have the exhaust for it cats and all. 700 obo
