dude, just disconnect the battery and touch the CABLES together. Don't bridge the distance between battery poles, you'll make a big light show. Leave it disconnected for about 15 minutes or so and that should do it.

per the manual.

disconnect the battery for 15 minutes
reconnect the battery and start the vehicle
let idle until warm
turn A/C on and idle for 5 minutes
drive the vehicle for 10 miles

this is how ford says to reset the computer per the 04 owners manual.

from what I've read, there is no real need to disconnect your battery cable when resetting your computer. For that matter, you don't ever really have to reset your cars computer. It will recalibrate it's settings (within it's limits) automatically after analyzing the a/f ratios. If you install a new intake for instance, you computer quickly realizes that there is more air present in the combustion chamber and compensates with more fuel. You don't NEED to disconnect your cables to reset your computer, it will take care of itself........ atleast this is what I've read.

well i knew about disconecting the cable (which i did today) and the light was off but appeared again tonight. Im not worried about it at all, but if i wanted to effectively eliminate the problem.... get a MAF for 24+ lbs injectors, 24+ lbs injectors, MAYBE a fuel pump and a tune to make it run smooth and that should take car of the SES light.... or maybe i could just rip out the dash and snip the SES wire... he he he

BUT assuming that the fuel injection system is tuned so that at full throttle the injectors are pumping at maximum capacity to mix the correct a/f ratio, that means that an increase over stock airflow would be beyond what the system is capable of compesating for thus the SES light... Now i could be wrong say if at max throttle the injectors are only flowing say 15 lbs.... then the system should be able to increase the flow of fuel... but I dont build the cars so i dont know about how they are programmed.... anyone want to Fine tune me on this one????
