Anyone use any of the rebuilt injectors out there? New ones are any where from 40 to 60 dollars each and was going to change all 8 of mine.
I've seen some for $150.00 all and others for as mach as $480.00.
I'm not rich but don't want to put in something that is going to go bad in a month...
This is for a 2003 F150 5.4..

Thnx

 

What is leading you to changing any of them?
Good luck.

 

Been getting P0300 code and longer crank times to start. O2 sensor reading lean...
I replace plugs and coils 6 months ago. O2 sensors a couple months ago....
So I think I have a couple with low pressure or partially clogged...

 

I think I'd be checking for a vacuum leak at intake manifold area or air getting past the MAF sensor, like cracked or loose air inlet hose. Also an EGR valve stuck open.
a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

 

I would also try a good injector flush before replacing them. Might be just a little dirty.

 

And how is the fuel pump pressure and the fuel filter?

And when it throws the P0300 does the freeze frame data indicate low engine load or high engine load?
