On a OBDII AAA VR6, when do the fule injectors, plugs/wires, cat, and rad hoses go bad? I have done plenty of work on my car and want a heads up on what to look forward to fixing later on. I have over 100,000 miles on her. I have already fixxed my Coil pack, thermostat, wheel bearings, cleaned t-body, valve springs, timing chains, clutch, and fixed some holes in my rad hoses. What other fun stuff do i have to look forward to?
