You're right on the injectors, but besides the pulleys you don't leave much left...
My wife drove a couple hundred miles down into Mississippi and when see got to her destination, she said it was idling funny and had burnt rubber smell to it. I had changed the belts about 6 months prior, but also didn't change the pulleys. Well the accesory tensoner bearing had failed and eventually heated up and destroyed the plastic. Of course she was driving non-stop for a couple of hours and gave the pulley a long time to heat up like that and fail. It wasn't until she got to her destination that she smelt the rubber.
Between the age and mileage, those pulleys are still a good suspect.
My guess would need you to pull both belts and inspect all four pulleys. Most would say you should belts when ever you change the belts...
