I have a '99 SR5 with 195m miles. The body is in excellent shape. its all original and its never been it. The interior is in decent shape. It has a bad injector on 6. It also needs a cat and a rear pinion bearing. Its also do for a timing belt. New injectors are probably $1200. An engine rebuild is $5 grand and would cover everything (except the rear pinion bearing) I could do one or the other or nothing. What would you guys do?
