Hello, I’m new to the forum. I have the following problem with my Swedes. When I step on the accelerator pedal in the standing gas, it jiggles once before the speed shoots high. When starting it takes off in the lower speed range bad gas. The following parts have been replaced in recent years: spark plugs, ignition distributor, ignition fingers, ignition coil, ignition cable set, new sensor intake air temperature, new oil trap, vacuum hoses tested, new knock sensors, new gasoline filter, new tempera tursensor, map sensor new. I would be grateful if you had another idea. Thanks already in advance.
