I would start with discerning if there are any modifications done/previous tune, check voltages, pulling the spark plugs and checking their health.So I recently bought a evo x with 8,000 miles on it. It’s a 2010 gsr when I try to start it I just cranks for 3 seconds I stop and do it again and it starts right away and the car has a rough idle and when I turn the ac on the idle gets even rougher

8,000 or 80,000 original miles? That's bonkers.. I thought my '15 had low miles at 36k lol!
