How much it cost to get them to check them? Is it something i could do

 

Since prices vary from dealer to dealer its best for you to call yours.....

if you're mechanically skilled you can check them....perform this on a cold motor only

I'm not responsible for any fuel leakage or breakage....perform at your own risk!!!

1st clean area around injectors....used compressed air to blow away debris

2nd remove fuel rail retainer bolts/screws

3rd pull up on rails in line with the direction of the injectors....you might have to wiggle the rail slightly....

4th prop/tie them up so that paper towels or napkins can be laid under the injectors

5th turn key to the run position BUT DO NOT START..... listen for the fuel pump to prime

6th look at napkins paper towel for signs of drips or injector spraying

7th if one is found bad replace all of them....there's clips on the fuel rail that need to be released to get them out

8th to reassembled lightly coat the injector orings with motor oil and gently but firmly press the rail evenly down

9th reinstall fuel rail retainer bolts/screws




personally I'd go the warranty route first if your truck's under 120,000 miles

 

The ford place said it wouldnt be the injectors since there were no other symptomslike a misfire. He said to just replace the cats, and spark plugs.

 

What would make the light go on and off though? Mine does that but I know I have an exhaust leak.

 

Maybe i have an exhaust leak and cant hear it.

 

An exhaust leak makes a consistent tick tick tick tick. It's really hard to not hear.

 

Nope dont have one, do have a tic but dont thinik its an exhaust leak just the infamous tic

 

Another tick is the fuel injectors firing but it's a different sound than an exhaust leak tick and the fuel injector tick is completely normal. The 5.4 cam phaser noise is more of a knock at warm idle. Mine does all three!

 

Onlyhad mine for a bout month and so far i love it( first full size truck) but damn its giving me a headache.

 

Pull the codes again - you don't know for sure it's the same code.

Cats are warrantied to 8 yr/80k miles except in California under the emissions warranty. If the spark plugs are shot that's YOUR problem, and it can be a REAL problem on a 5.4 3 valve.

 

I went nd got the code pulled a couple of time and its the sam coed. Everyone says the cats but would it be the cats if it keeps coming on and going off? Ford dealership wants to charge $350 to replace the spark plugs.

 

$350 isn't too bad for a plug change as long as it includes broken plug extraction.

 

Well i got the magnaflow cats put on today and also a magnapack but they didnt reset te code, how will it take the check engine light to go off?

 

If the CEL is still on, you still have an issue.
