    Well i got the engine to properly fast idle and idle normally, now it still bucks after every gear after i let off of the clutch and stay in the same gear to maintain speed it still bucks the temp sensor has been replaced which like i said has taken care of the idle except i also forgot to mention that it has a rough idle not real real bad but noticeable
