I first want thank everyone for all the knowledge and insight I've gained from the fourm in the last week. The engine is idling around 1600 at start and continues when driving. I've cleaned mas, iac ,and throttle body. Replaced O2 s1 B2 with denso sensor from rockauto. Replaced pcv valve,air filter ,spark plugs, per owner's manual. Truck has 250,000 miles. Thank all of you for the information on how to do all of those repairs. Here is a screenshot off of tech stream if it helps any. Thank you all so much for your time this is a great community and I appreciate being a part of it.
