ECU code

[jms19delta]

My ecu gave me the codes "21"

I just tested my coil packs. I have a rb25det series 2. I checked the packs by placing the positive probe on the first prong and the neg on the second prong (as if you are looking at the coil pack upright and the prongs being numbered 1,2,3). I got 1.6 k ohms in 5 of them and 1.7 in 1. I believe I read that they are supposed to be 0.7 ohms. Obviously they are bad. Anybody know where to get a full set cheap? I'm fine with a used set for now...just need to car running asap!

I doubt all 6 would go bad at once? What's your problem with the car?

[jms19delta]

refer to this thread...zer...blems

On a rb20, code 21 ignition circut. Not sure exactly what that means, could be a possible missfire. Does the car miss, or just idle very low. Your timing may have slipped causing a power loss... can't hurt to check that.

check the ignitor or the cas, but most likely its the ignitor.

[jms19delta]

No ignitor...its a series 2

[jms19delta]

call you? got some info for me or what?

[abubika345]

Yeah I can help you out I think with testing and such. Unless your regulator is not returning fuel fast enough, a fuel pump wont cause a rich condition.
