My 2006 savana 2500 4.8 started doing that and i replaced the tps on the throttle body i was so excited because it had more power than when it was brand new then one week later wah wah wah wha.. Went downhill from there ive done tune up intakemanifold gasket and just aboit every sensor i can think of and still lean conditions .maf sensor new.map sensor new purge vent valve new. Crank sensor new..out of money and soon out of business with it being a service van. Live and learn. Should have listend to my dad and got a ford but i figured if the government likes them for drpendsbility cant go wrong.
