does any body have an idea why my 03 accelerates faster at 3/4 throttle than full throttle. It has no mods and is an auto. I'm not saying that its running wrong but when you lay the pedal all the way down it feel kinda like its not gettin enough air or fuel.

Clean your injectors

 

ill give it a try thanks

 

Shouldn't do that at all, should accellerate the harder you push in on the throttle. Injector cleaner wouldn't hurt though.

 

I was wondering guys If injector cleaning can be done by myself. I wasnt thinking about pouring the bottle into the tank but is it possible to pressure clean them to get all the build up out??

 

Well a good quick and mostly effective way to clean the injectors would be to use a product called Seafoam. It's literally one of those "miracle in a can" type products... but it's a no bullshiit product that actually works.

 

i use chevron techron fuel cleaner ,i buyit at the local auto parts store, it cleans your entire fuel system instead of just cleaning the injectors. its good stuff .

 

i never have injectors on long enough to have them needing to be cleaned.

 

Well that's what happens when you're under your hood every other weekend.

 

1999-2004 mustangs have a WOT tune which basiclly increses shift firmness makes the car run leaner and alter the timing curve, From what I am hearing it sounds like here is something wrong with your ECU you may have a dealership in town that you could take it to and they could flash it, some will, some won't, that may fix the problem.
