Typical 100,000 mile maintenance
I have a bone stock LT1 and am just checking to see what I need to do to get it back into shape for this year. The car stutters a bit at low RPMs (1000-1500) right now, planning on replacing the plugs and wires. What I'm not sure on is the opti. It's the vented Opti ('97) and seems to be running fine - is this one of those things where if it's not broken, I shouldn't touch it? Or should I replace that too?
Also, any other typical maintenance that should be done at this mileage?
