I was on the freeway and it was fine, then suddenly it starts surging, like I was on and off the gas pedal. It does it at idle and at speed. I cleaned fuel filter and replaced the pump, no change. A few days before after I ran the front tank empty it started dying when I let off the gas and I took off the fuel filter and sprayed it with brake cleaner and blew it out with compressed air and replaced it, and it seemed to work. The day that the surge started I had passed Oregon DEQ emissions test.
