Hey everyone so I have a problem that has me stumped. My Outback has issue at about 3000 rpm, It starts bucking usually just in 3rd gear (MT) when I let my foot off the gas and going down a hill is when its very noticeable. When it starts to buck the RPM fluctuates as well. The fluctuation is very small maybe as much as 500 rpm. This problem usually goes away once the vehicle is warmed up. Only first few mins of driving. There is no check engine light. The clutch is in good condition and doesn't slip at all. So far I have changed spark plugs but that didn't help. Wires are good too. Anyone else experience this? Im thinking it is fuel related because fuel is generally thicker when cold. I don't think its a transmission problem either because it shifts good and once warm it preforms great. Any help would be GREAT THANKS!
