i honnestly have no clue when the last tune up was, ive only had the car for about 2 weeks all i did was weld the diff and drift it, kinda beating on it for a bit, but the guy i got it from didnt drive it sense 2007 i dont even know where to begian, it gets stark some times,i was thinking its a leak it could be a coolent issue, also as i forgot to add to the first post, if i drive the car before ti warms up its laggy and dies and will not start, ive had to leave my in the parking lot of where i work for an entire day before it would start, i changed the starter. spark plugs are good timming is fine theres no oil in the cap, im new to nissan, im fimilay with honda, im trying to get my hands on a sr swap or go ka-t but for now, i just need to get to work.
