ok heres the issue my car is idiling rough it feels like gotta a big cam in it or something but if i am idiling and push in the break my car idle goes down quite a bit and the lights go dim if i let up on brake my lightes brighten now if i put it in first gear and take off my speedo will stay on zero for a min then it when im going like 10 mph then it will jump up to ten and work fine till i idle again. and lastly when im driving and i switch gears or when i take it out of gear the rpms got all the way down to 500 then back up to 1100 then to 800 where it stays. what do you guys think?
