CEL but no code

[Flipnirish]

Did a lot of searching and came up with nothing. I have a 96 240sx all stock no mods w/ KA24DE. The Check engine light is on and flickers. I've hooked up two different code readers to the obd II port. Both read no codes, but they show TPS is 100%, MAF at 73.02 which is wrong as well, and engine temp at 401 which is ridiculous. The car was at idle when I checked for engine readings. I checked for codes at ACC on.

I'm so stumped and don't know what else to check. Could this be a bad ECU?

Oh forgot, while at idle, car sits at 1553 then dips to 840ish then back.

TIA for any help,
Tommy

it seems like the ecu
u should hook up consult it helps better

I just did some reading about the "Consult." But shouldn't any obd II scanner work? And are dealerships the only place that have these? What a monopoly!

Found my problem! Went in for the ECU, uninstalled it and opened her up. Looky what I found, a s*** ton of bugs!

Installed another ecu and no more CEL!!

FIXED!
