95 problems, need quick help

[Aaron Dickinson]

Hello All

my truck has a knocking noise and runs real rough at low rpms. It has a hard time getting going under load, like it is choking out. Idles rough. It started having blue smoke at times a few months ago, which has gotten slowly worse. The fuel filter has been black the last couple times I changed it drained fuel bowl and it looked greenish gray. No cel and nothing changes when I unplug icp. Changed cps already, and all the fuel and air is clean and flowing well.

From my research here at the org it seems everything is pointing to injectors.

No access to diagnostic tools

Need help quick, gotta make a living with this pickup

Thanks

Injector o-rings probably split and leaking. Will have to pull injectors and install an o-ring kit.

See if this helps you out.

figured out at least part of the problem, the plug on the intake was unplugged

but I still think my o rings are needed repair. Will it harm the engine to run it for a while with bad o rings?

Did you check your oil level? The injectors dont run very well w/out oil....my old white truck (sold) was having similar problems eventually I found out that it had been burning oil and was running so low it didnt have enough oil to fire the injectors....FAIL
