I have a 2002 TB LS w/ 133k that I've just bought. At highway speeds (50-70mph) the RPMS are sitting at around 1500 to 1600 on level road. If i start to speed up slowly, the RPMs will surge back and forth between 1500 and 2000 RPMs. If I give it a little more boot to beyond 2000 RPMs it will stop surging and speed up normally. I'm new to this engine so I'm not sure if this is a big problem or not. I can say that I will be replacing the fan clutch soon as it sounds like a jet engine from time to time, but I don't really think there's a link there. Any help will be greatly appreciated!
