Hey guys,
The past 5 times I've gone out and driven my car for 40 minutes or more EXACTLY, my speedo goes crazy, then dies, and I throw a code. If I turn my car off, then on, the code dissapears. Really wierd.
I've tried to get the code to come on constantly, but it won't stay.
I've recently changed my battery, alternator, and thermostat, so I don't think it's anything to do with those.
Now, my question is: If I throw a code, is there some sort of memory built into the ECU that will remember it? Basically, if I'm not currently throwing a code, does the ECU keep a record of the last one thrown? Meaning, can I flash the ECU to diagnose the code if my engine light isn't currently on?
Thanks for any help.
If it matters, I'm running a JDM P30 OBD1
