Hey guys, my 1986 Mazda 626 2.0i Manual Transmission is jumpy throughout 1st-3rd gear. It's jumpy in the same way when you pop the clutch and don't give it enough gas. It's goes from 2k to 2.5 then straight to 3k until I shift, then it does it again through second and third. I've put new gear oil in the transmission, replaced the fuel filter, I really don't want to fork out the money to bring it to a mechanic. If you guys need any more information just ask, my name's Matt. Thanks for your help.
