Hi, questions about DTC
I have a MY 94
The car has been running bad for sometimes, it starts up perfect, but it doesnt feel like its running on all the 8 cylinders, i have new plugs and soon going to instal new opti and cables
When i accelerate it doesnt feel like the 300 hp it should be, it hesitates (not bad) and feel like a 190 hp car if you now what i mean
Ive got follwing codes by jumping nr 4 and 12 at the OBD
1. H51 EPROM Programming Error
4. ---
9. H63? isnt this a oxygen sensor code? and what is it doin under 9 (asr/abs)?
i dont understand the nr 51 code?
Regards
Simon

On your 94, DTC 51, EEPROM error can only be caused by a problem in the PCM as far as I know. If it has been "tuned" I would have the tuner recheck his work, otherwise I expect you need a PCM. The code can be caused by a loose EEPROM on earlier cars but that does not apply to a 94.
DTC 63 would be an O2 sensor code in the PCM but in the ABS (EBTCM) module it is for valve solenoid relay circuit malfunction and can be caused by a blown brake hydraulics fuse or other problems in the circuit. Follow the diagnostic tree in the factory service manual for the correct troubleshooting procedure, good luck.
