Random & Intermittent Fuel? Problem
Just driving along and the RPMs will drop to almost nothing then after some time return to normal, but feels like it's going to stall. If I engage the clutch and pump the gas hard I can keep it from stalling. After 5 to 30 seconds of no power and giving it gas the RPMs soar, like the engine just received a huge burst of gas and then car runs OK. Happens very randomly, sometimes every couple of minutes and sometimes not for hours. Usually occurs at lower speeds rather than highway speeds.
Changed fuel filter, still occurring. Brought to LR Dealer, they could not get the problem to occur while in their hands and could not diagnose. What should I look at next? Thanks in advance.
