Just Started about a week ago. At idle and during warm up the idle will jump about 100 rpms up and down. It'll go from 750/800 down to 650-700 in a continuous cycle that is about 10 secs long. My amp died at around the same time but it doesnt change anything now that its out. Its a 94 ex that was stored for 6-8 months, its on its second tank of gas now, any ideas?

 

Could a clogged fuel filter cause something like this. I might try some of that BG44k stuff.
