How many miles on the injectors?
The 4Runner has over 278000 miles on it. I was told the engine was rebuilt 50000 miles ago. The fuel injector look like they may be the original injectors. The seal to the intake, on number 1 injector was cracked and the paint was washed off the injector body. I replaced the seals, but now I think I should have replaced the injectors too.
