I'm currently in the process of bringing my car back to life after the amount of negligence I've been giving it for the past few months It's currently overheating due to a cracked radiator since December (yes I added coolant before every drive and in between) and now recently started to have a really rough idle. It feels like half the engine is missing but when I accelerate it smooths out. Sometimes it just dies at idle regardless if it runs smooth or rough but it dosent die out every time. I broke the right side valve cover breather hose right at the T splitter coming off the intake. Does anyone know if I can buy this hose separately or must I replace the whole assembly? I also noticed that the boot where the pcv valve hose connects into the back of the engine has a split making a hissing sound. This could probably be the cause of both banks running lean (P0171 P0174). The hose itself is fine however. Can I purchase this boot separately? I must say, after neglecting to do VCG's, coils, and radiator/plumbing, the car dosen't want to give up. Probably not the best car around but it sure has a lot of potential. Edit: I forgot to mention, if I rev the car abruptly at idle, I hear a rattle. Sorta like something is loose. I don't have a second pair of ears to help me out on this one. It's a v6 Gen 1.
