Well here is the quick version of the story. I'm the second owner of this vehicle. Have owned it since '94. Have always had her maintained on schedule. She currently has 346K miles on her. The compression is very good. She has always started up easily and quickly.
Lately, (and it could be biodiesel related) she seems to lack power at freeway speeds (uphill and passing) especially noticeable at altitude...more than in the past.
I have changed fuel filters recently but perhaps need to again.
Just changed the injectors and she idles smoother when cold...but shakes somewhat when warm at idle.
Have replaced rack damper bolt. btw, it appears my primer pump leaks a little when pumping...can that be a source for an air leak??
I'm thinking it could be the injection pump? I'm not sure what else to check...performance is good off the line.
Any thoughts??
Thanks,
Eric.
