So i picked up an 86 XJ 2.8. Okay so yes i now know the engines are crap. It starts fine and idles okay. It boggs and sputters when giving it gas. I put a new fuel pump on there and just had the carb rebuilt and reinstalled. Still running like crap. I'm going to start replacing the vacuum lines and probably put a new coil in. The jeep was sitting for 10 years in a garage and only has 45K original miles. Its all original except for the wheels. I'm just going to sell it once I get it running good(if thats possible).
Does anyone know exactly what size vacuum line it has? Any help would be greatly appreciated
