OK, the only thing different is a new engine harness...going through a mil spec connector but please read, i seriously doubt its that. I have tried 2 other distributors and it still pops up code 8, i can clear the code and crank the car and the code NEVER comes back until after the engine is not running but the key is on, it only happens on key on engine off. I have ohm'd out the sensor at the dizzy plug and the ECU plug, i get the same readings (370ish ohms), i have checked continuity and no wires are shorting to ground and it checks all the way back to the dizzy plug from the ecu. WTF?

 

most likely a wiring problem seen alot of problems with the custom harnesses

 

Try the ecu in another vehicle to ensure the issue isn't related to the ecu.
(I highly doubt the issue is related to the ecu).

 

i put a stock ecu in and it still threw the code. like i said i have tracked down the wiring, and it all goes where its supposed to, and all ohms out as it should and is not shorted to ground!

 

has to be wiring if everything else works in other cars

 

ok so yeah it could be wiring, but if i cant find a fault in the wiring, being its the simplest wiring ever, wtf am i supposed to do lol.

 

one guy said on the hondata forum "It sounds like your harness is powering the ECU at all times and is triggering the code because it thinks it should be running."

What does anyone make of that...
Is the ECU not supposed to get power at all time with key on engine off though?? I mean you get check engine lights in the same position on any other car?
Doesn't make much sense to me.

 

the ecu gets power in the on position if it didnt then how would you check for codes , a simple way to check to see if its the wiring run a single wire from the top dead center sensor to the ecu to see if the code goes away

 

im going to do some work with it tomorrow. Heres a note. When i first started trying to get the car to run, i never had this problem, and i worked with it for 20 minutes playing with stuff once i got it running and such. Its when my tuner made his map and tuned it that the problem started. Im not saying he created the problem himself but maybe some weird glitch could be causing it with the map....is it possible for a corrupt map to randomly throw a cel for no reason and only when the car is sitting with the key on and not running. Just wondering if its possible, NOT if its ever happened before. Im going to load a virgin map into the ECU tomorrow to see what happens. I never thought to try it. Im also taking a spare s300 to see if it does it as well.
