Tuneup
By Tommyva
2017 1500 Larimie 5.7 I just turned 95,000 miles. Gas mileage was dropping off so I replaced the plugs, Intake temp sensor, cleaned throttle body, new air filter and ourge valve to clear a code. I can only get 20 miles to the gallon on straight highway driving and at best 14 mpg in town. Any suggestions on anything I missed?
