so having stopped using the car and hopefully in the process of returning it im now on the busa full time but where its been stood for intermittent amounts of time idle and low rpm it runs rough but at WOT it runs very well, its had a good 6 or 7 tanks worth of fuel through it since iv started using it full time yet it runs no better.
when cold it idles reasonably ok at around 1300-1500rpm when hot it hunts/misses between 1600-1800rpm and anywhere below 4k its very stuttery and missy but anything over 4k to the red line it runs sweet as could be, it has a full yoshi system and power commander along with a logic quick shifter, and occassionally it doesnt like starting but thats due to cheapo levers playing silly buggers with the clutch switch, not checked it but pretty sure the battery is good as its been on optimate alot.
i know it could do with a service but just wondering if anyone in the know could point me anywhere else to be checking as possible causes.
i know at idle it is prob running very rich as the exhaust smells pretty strong of fuel but as with everything nowadays its all bloody electronic and im not great with electronics things.
