You're right.. I was actually just reminded about additional warranty coverage for 11 yrs or 120,000 miles for the fuel injectors for the 2005 3V engines. The symptoms are "... check engine light illumination along with hard starting or rough running..". Apparently the injectors may stick in the open or closed position.
Not sure if this is what I am experiencing, but definitely worth looking in to.

 

My 2004 has 85,500 on it. I have changed the fuel filter, spark plugs, coil packs, air filter, has rebuilt trans with shift kit, cam phasers, vct solanoids, cam sensors, cam sensor wire pig tails, long tube header kit, high flow cats. service on it recently. Between 3000 and 3500 RPM's (roughly that range) the engine bogs at wot. It does it in every gear. If you go from a dead stop at wot, it spins the tires and accelerates until it hits about 3000, then acts like it isn't getting fuel, bogs, sounds terrible. If I go to pass someone, it does the same thing in that rpm range. It does it in every gear and does it 100% of the time. I just purchased a SCT tuner with custom tunes made for my truck, but even when i return to stock, it always acts the same.

I have spent way too much money on this truck already so anything will help me at this point. I'm tired of working on it..

I am out of ideas.. PLEASE HELP, dealer does not know what to tell me....

 

Have you cleaned the MAF and throttle body?

 

I am going to check the MAF tomorrow morning, thank you for the reply!

 

I got rid of the problem.... Traded the ol' girl for a 2014 XLT screw. So now I have an Edge evolution without a compatible truck to put it in. Could anyone direct me to where I can put it up for sale? Thanks in advance.
