2005 Ford Freestar check engine light

7 posts in this topic

Check engine light came on, runs rough. Mrs boatfixer takes it to a shop that has done work for me before and I trust them. Tech took a quick scan and said #2 was mis-firing. Said pretty sure it's an injector, probably not a coil. Question, Can't the fancy schmancy scanner tell the difference between an ignition and fuel problem? She is taking it back in tomorrow for a better look. What can I expect to pay for cleaning injectors?

No!

The "fancy schmancy scanner" cannot tell you anything more than the cylinder that the misfire is on (P0302 - #2 misfire). Its up to the tech to put his/her brain to work to rule out all the possibilities except the one that is causing the problem. These possibilities can be, a vacuum leak, burnt valve, burnt piston, any other source of poor compression, ad spark plug, bad valve seals (oil foiling of the plug), week injector, bad coil, wiring between the PCM and affected coil/injector, PCM, worn cam, bad lifter, and the list goes on and on. It would be nice if there was a "fancy schmancy scanner" though!

If this is the 3.0 DOHC 24 valve engine it has coil over coils. One coil per cylinder. In my experience I have replaced way more coils than injectors on this engine. Unfortunately I think that the # 2 coil is under the plenum so it can not easily be moved to another cylinder to see if the misfire follows the coil or not. Typically you can use a spark tester and watch the spark fail as you crank it over (the other coils need to be disconnected so the vehicle will not start with the plenum off).

Oops! I forgot to add it comes and goes. Not there all the time. And it's a 3.9l. My bad!

Airjer is correct, I too would guess coil pack over injector. You can hook up tools te determine if it is a coil causing the miss, or an injector. But it is easier to swap part to a different cyl. and see if the miss moves to the other cyl

I would also say C.O.P...

I would think intake leaking, before a failed inj...

Whew!!! Dirty injectors. Runs great and Mrs. B is happy again.

WOW that hurts!! I guess we all get a swing and a miss every once and a while. Glad to hear it was a simple and probably relatively inexpensive to repair!

    • Hey @rl_sd who had the meat on sale? Looks great btw
    • chicks maybe exploring what the beak is for
    •   You can also be a little creative with the leftover meat.  For example: The wife and I will whip up a spanish rice mixed in with the pork and make Enchiladas or heat the pork on the stove top, mix in some BBQ sauce and make quesadillas (the grandkids love them).   There's more to pulled pork than sandwiches.  
    • that is great!!!!   good for you guys!!!!
    • Your right rs_ld,  a full smoker is the way to go, leftovers can always be frozen and re heated..good eats.
    • 195 degrees on these butts. Like they say, if you are going to spend 9 hrs smoking 5# of meat, you just as well spend the same amount of time smoking 45#. The local grocery had these on sale so had a few friends take the offer to throw a roast on for them. Took two off early for slicing  Pulling the rest cost them each a beer though!
    • Very good stuff, kinda tasted like ribs with this recipe,  I'll keep at it til I find the right one!! Good luck moon lake!!
    • It will be interesting to see how the Warriors react in free agency.  Will they be able to keep the team together?  It seems like all these guys value winning above a paycheck so they might be willing to sign deals that will still allow the team flexibility to keep good role players around them.    
    • That's too bad.  The fish were ON FIRE up there.  I went out with my dad and uncle with our tiller walleye boat, and hardly a clue what we were doing, and we crushed them!  Ended up with 118 pounds of packaged salmon fillets.  I think I can honestly say it was the most fun fishing trip I've had in my life.  Here's my biggest of the trip, 25 pounds.    
    •   It's amazing to see a thoroughly talented team like Cleveland just get dissected like a back alley pick up team. I agree--GS will be THE team to beat for several more years if they keep their nucleus. I think we can make them sweat a little bit now, though, so that's pretty exciting for a change!
