Injector color/MAF

Nixon1 · 01-28-2003, 11:02 PM

19#/hr injectors are stock right? Is orange the code for those? Just wondering..trying to nail down why my gas mileage is so horrific, besides the cam and 4.11's. It's got orange injectors, which I THINK are stock size..but new chrome fuel rails.. Also, is there a way to tell the calibration, flow capacity, blah blah blah for an MAF? Like using #'s on it or anything? Mine's got a buttload of numbers that I scribbled down just in case.. I just wanted to make sure neither have been swapped so they match together...the MAF looks stock, says Ford on it...and like I said, the injectors are orange. Thanks..

orange=19lb blue=24lb red=30lb lime green=42lb

if the mass air is ford and it looks stock it probably is, i believe ford calibrates the computer for bigger injectors not the mass air.

Actually you do have to calibrate the MAF to the injectors. Also, the fuel rails are chrome ( if not, they look like it) from the factory.

What i think sn95 was trying to say is when the car comes with different injectors from the factory like a cobra they use the same hot wire as a gt but the compensation is done in the ecu not the mass air hot wire.
