Just wondering, a buddy of mine who is supposedly a ford know-it-all told me today that my injectors on my '02 4.6were the wrong size, just by looking at the color. I know that the stock size should be 19lb/hr. , or at least was for the 5.0. He then proceeded to tell me that the ones in my car were 24lb/hr. Are they color coded, and if they are, what is the cheat sheet, or where can i find it?

ok, thanks. its going to the dealership Mon., and i will be asking them to verify the MAF / injector match. thanks for the help ya'll
why, are you having problems with the car?
Having a maf "matched" to a certian jnjector is a myth. This comes from the adjustable maf setups like the C&L where you can change the internal tube size to change the reading, thus faking out the ECM and tuning the car. It can also be used to lower the sampling area on these aftermarket mafs so a higher horsepower car doens't peg them.
Unless its an aftermarket maf, there isn't anyway to "tune" the maf to the injectors, its all done in the ECM. If its an aftermarket maf, the dealership isn't going to know anything about it anyway.
yeah, been having issues with the car running "like a rich tuned carb." im dumping alot of fuel, and getting really poor fuel mileage. anyways, ford gets it back tomorrow to do some other work, so im gonna have them check it out.
Just get it tuned. When ford upgraded the injectors they also upgraded the ecu. If you go to the dealer they are just gonna say some bs and charge you abunch of money when its probablly best to just get your car tuned.
