Well I got a new tank of gas, gone about 70 miles on it so far, and it's still there. Now the idle is getting rich and jumping around a lot. It'll rev itself up and down from like 500-2000rpms sometimes. I feel like a ricer whenever I'm at a stoplight because people keep looking at me thinking I'm trying to race. Sometimes it will idle fine, and other times it'll be really lumpy and rich. I'm very confused.
