pulled a code
 

ok, my friend has a 94 gt, mith mods as follows: Eibach Sportline 2" springs, Bullitt 17x9 wheels, Mac Cold Air kit, BBK 70MM Throttle Body, Pro-M Remote Optimizer, TrickFlow upper and lower intake, Mac Unequal Length Headers, Mac Prochamber, Bassani Forward exit catback, MSD 6AL Ignition system, 8MM Trickflow wires, 255# BBK Fuel Pump, Adjustable fuel pressure regulator, Mac Underdrive pullies, 4.10 Motorsports gears, white face guages, clear corners, cobra r clutch, Steeda Adjustable & quadrant, autometer air/fuel & water. His check engine light would come on occasionally, he thought no big deal. He put on a afpr and now it stays on constantly, so last night I bring my scanner up to his house and run it for codes, I pulled a 123 (think that was the number) but it was for the tps voltage beyond maximum limit or range or something like that, no big deal. Heres the one im wondering about, code 998 means hard fault present, wtf is a hard fault, in my 7 years or working on mustangs I have never heard of such a thing, any help here would be great.

Sorry I can't help you with your code problem, but I had a question about your sig. What does the 283 stand for? I can't be your motor. The SN-95 stangs came with 281's. :confused:

I thought the SN95's came with 302's. :confused:

1994 and 1995 had 5.0 (302), but the 96-98's have 4.6 (281)

Saleen number?

Take care,

I'm, pretty sure that 123 means that its running rich.

I didn't think Saleen differed from Ford's CI :confused:

Saleen serial number

ah, got ya ;) almost forgot about those.....

:)

BTW, 123 is a TPS code, and it should be corrected before you go any farther. Code 998 is not good, but you have to eliminate the TPS code first. Don't forget to reset the ECM after correcting the TPS code, then run KOEO codes again. If you get a 111, then run the KOER codes, and see if 998 is still there. Post the results.

Take care,
