Each time I start my car, it sputters and a slight back fire. revving the engine and it almosts stalls. I have replaced all of the vacuum lines but I do hear a "sucking" noise.
after 5-10 minutes. It runs fine. if I drive it 2 hours later it is ok... If I wait 5 hours, same thing.
I am pretty sure it is a faulty vacuum hose but it running fine after 5 minutes is throwing me a little bit, does anyone have a diagram which shows all vacuum hoses?
