Engine Loping


On my last trip I noticed a lack of power or hesitation in acceleration.I held the accelerator down to floor steady and the engine speed flucuated fast and slow fast and slow. Almost as if the fuel was intermittantly cut off in about 2 second intervals. ( High rpm, low rpm etc.) I haul a small 16' trailer and in running it seemed that this problem was lack of power with this load on it. However I have checked this affect since then only while it sits in the garage so don't know what the problem might be. I have been told it sounds like a vacumn leak or fuel filter plug up, however I change filters before any lengthy trips and regularly. It is a G20, Sport Van, 351, 8 cyl, 1995 FI
