2002 ram 1500 4.7l, it is a 3rd gen. What should the normal load pct be at idle? My scanner shows 3.5% which I feel is low, shouldn’t it be more like 20%? My truck has been driving me nuts, it’s been surging at idle. I can’t find a vac leak in the lines or intake manifold, I’ve replaced the IAC, evap purge canister, MAP sensor, spark plugs and cleaned the PCV valve. I did a TPS relearn which worked until I drove about 15 km and then the surges started again. I replaced the TPS sensor in October so I’m not sure if that’s the issue. The TP% is 12 at idle.
