What should i do about fuel injectors? Should i just clean them, or should i purchase new ones. If i should get new ones, what type and size, and where from. Thanks

 

Get them cleaned at most all diesel shops. They'll let you know if they can clean them or you need new ones.

 

How hard are they to get out?

 

Not hard at all, Five 14mm nuts on the manifold side. Two 12mm on the drivers side under the dynamic chamber, yank the throttle cable and cruise cable off the manifold. Take your vacuum hoses and two coolant hoses off. Slide the oil metering pump rod off. The 2 injectors on the fuel rail are held down with two more 14mm bolts that are different lengths. That's about it. I can take mine off in 5 minutes, granted the engine is cold. = )
