my g/fs 95 stang has its engine light on.
the car overheated, as the rad fan was seized. steam came out the hood and all that not-so-good stuff. she shut it off right away and we added water to fill it up. anyway, the rad fan was replaced and the car has ran great since.
i disconnected the battery (both terminals) for several minutes, in an attempt to reset the computer. when i put the battery back in and started the car (only for 30 sec). just after the next time the car was started the light came back on.

am i not resetting the computer, or could there be something else wrong??
how can i check what codes are present with out paying $150 at ford??

 

Take it to an Auto Zone or Advanced Auto and they will pull the code(s) for you for free. They will give you a print-out too I think.

there aren't any auto zone's in canada, and basically i just want to know how to reset the car's computer. in my car you have to remove the radio fuse for a few minutes.

how do you do it in a mustang?

 

Try posting this at www.cmoc.ca or www.gtamc.com , mustang gurus may help.

 

Bro why would you NOT want to know what code it is ??? and for the record a brand new code reader is like 29.00 - 49.00. OR dont you know anyone with a Diablo Predator or a SCT X Cal that can read it AND RESET IT.

Good Luck

 

disconnect the battery for 15-30 minutes. connect the battery, let idle do not rev it at all let the computer re learn its parameters.. I have been a 5.0 guy all my life that is how I always did it..

 

i borrowed an obd-II reader (95 3.8L stangs are obd2 and 95 GT's are obd1, i don't know why ford did that) from crappy tire (returned when finished, lol) and found the codes to be:
DTC P0171, left bank, and DTC P0174, right bank, indicate the fuel/air ratio is too lean. The system is at the rich limit.

the engine light came on when the car overheated. i'm not sure why it would at that particular time and the car seems to run fine. any hints as to why this code may have come in???
oh, and i cleared it and am waiting to see if it comes back or was just and intermitant thing.

 

k, i think i found the problem...keeping my fingers crossed that it is!
the line just after the MAF on the intake line that runs to the oil filler cap was disconnected. i reconnected the hose and disconnected the battery to re-set the computer. i reconnected about a half hour later. i also tried turned on the lights to put a load on the power system as was suggested to do, before i reconnected the battery.
i will be driving the car to let it run through its drive cycle to see if it comes back on.
