has anybody had fuel injector problems and if so what were your symptoms and what did you do to fix the problem...i have a rough idle and a missfire in 4 and 6 and i have tried alot of things to fix the problem but have not tried changing the fuel injectors yet..

 

what have you tried already?

 

i have tried changing the plugs, wires, coil pack, and fuel filter, messing with the idle bolt and fuel injector cleaner

Check your compression.

 

Check the plugs - if 2 are dry and one is wet, the wet plug has a bad injector (stuck open).
If two in the bank are wet and one is dry, the dry one is not opening.

Try using a long screwdriver as a "stethescope" and listen to be sure it is opening.
If needed, I have some already cleaned - singles and sets.

 

I had two injectors go. You've done everything I did, check plugs and wires, injector cleaner, etc. I finally just had to replace them. One was a electronic failure and the other was just totally clogged. Hope this helps you out. FYI, a Haynes manual is a definite help if one is under the intake manifold, and if you are in there I recommend a new plenum gasket since you're in there as well.

 

thanx hot wheels..will do

 

I've been able to reuse plenum gaskets 4-5x with no issues, but it doesn't hurt to have one on hand. If you don't use it you can return them (normally). The gasket is coated with a release agent, and unless it sticks/tears, you'll be fine...

 

I just figured I was in there and why take a chance you know? Especially since previous owners didn't take the greatest care in maintaining the truck.
