02 Yukon Denali
Posted: Tue Dec 04, 2012 8:22 pm
I have a question. What should an 02 Denali be idling at? Its a 6.0 and has been surging and stalling. My wife drives the yukon to and from work, since its not even 2 miles a day. The fuel pump went out about a month ago. I changed that and the fuel filter. I took all the engine covers off and replaced the PCV valve and the hoses connect the PCV to the plastic pipe and the pipe to the intake. Last year I put on taylor wires and NGK I think TR5N plugs. I just had the battery tested and put a Duralast gold from AZ in. I also put a cold air kit on. I just cleaned the Mass Air Sensor, but need to clean the throttle body yet.
There are no codes kicked off, it just stalls when she gets to a stop sign. Its idling about 500 now since I changed the PCV and hoses and cleaned the Mass air sensor.
If there are any other tips on getting the fuel mileage up, I sure would appreciate it. I am going to use this as the vehicle to tow my car to the track, I towed my dad's nova and my neighbors 74 chrysler and this truck had no problem pulling it.
