Throttle cable and housing may just need lubed. My 3.0 needs it about every 6 months. Last time I tried graphite (dry) lube in hopes of avoiding having the petroleum based lubricants 'cook off' inside the housing due to engine heat. So far, the graphite works 'OK', but it's not quite as slick as the SPL 100 lube. However, it's been about 5 months since I used the graphite and it's not sticking too badly. I may try the graphite route again this next time, too.
