I have a 93 5.7L v8 vandura that is running rough. It's surging at cruise speeds, jolting when you take off from stops, idling bad at first start and while in gear. My car can't maintain speed at cruise control setting and dies when you put it Into gear from park. My car also often times does not shift when it's supposed too when going down the road. I've replaced the vacuum hoses, MAP sensor, o2 sensor and fuel filter. It comes up with a PO44 lean fuel error code. Any ideas on what's wrong?
have the same problem?
