09-883 efi. If I start up and just take up I’ll have a major miss almost completely shutting off. If I let it warm up it won’t miss. Also, while in 1st, 2nd, and 3rd gears At about a 1/8- 1/4 twist(holding steady) it’ll miss. Changed plugs, wires, fuel pump hose, and ran several cans of cleaner through the tank.
