I have a 1996 Dodge Ram 1500 5.9L two wheel drive that has what sounds like a vacuum leak. The truck sucks air bad from the air/ idle control valve and I have replaced the control valve and the whole throttle body plate with a control valve on it. I have also changed the throttle position sensory, fuel injectors and the spark plugs. I have checked every vacuum line that I can find and still no luck. I had the fuel pressure checked and it is at 50 lbs of pressure plus the diagnostic test says that it is running lean yet you can smell that it is running rich and I have also gutted the catalytic converter. So do you have any idea what it is because everyone else tells me they have never seen a vehicle do this.
have the same problem?
