:help2: Next available appt. at dealer "6 days," thought I would try to get some idea's and help here. It started back in Sept. Loping idle for a few days then it cleared up until last week. Only when warm, idle jumps up about 200 rpm then almost dies before "catching it's breath" then repeating. has not set CEL, I have no way to pull codes. New fuel filters have not helped! Runs great off idle and at speed. Fingers stick installed 9 mos ago, all connections soldered. Edge EZ seems to mask it somewhat, "I have it off now for dealer appt." (they have to redo a pinion seal) Plan "B" is trying to clean MAF with some brake parts spray. Anything else I can try "at home?"
