I just acquired a 95 S10 Blazer with the Vortec V6 (this is the last year before the newer vortecs). It's got about 170k on the ticker right now. I know for sure I need to clean out the throttle body, is there anything else that could be cleaned/changed to help restore some of the power in the engine? It's had the air and fuel filter changed within the last year, fuel pump was changed about a year and a half ago, and the cat doesn't exist any more (got hollowed out by the previous owner). This is about the newest vehicle I've owned, and I'm really not too familiar with all the electronic crap (TBI is about the most electronics I've had in my vehicles), so any help would be greatly appreciated.
