hi guy
got a JDM bigport out of a jdm trueno
has idleing problem
idle jumps up n down, about 600 then 1100 then 600 then 1100, 600, 1100, 600, 1100 etc.....
heard it can be leads, sparks, idle sensor and timing but not sure which one
if you know what it is or how i can test if there fautly let me know
i cant replace 5-6 items when theres only something wrong with one.
thanks
