Hi everyone new on these forums, looked here alot. Tons of great help here, but I need some help with my 1990 ls400, its all stock, picked it up on the cheap with 190k miles on it. tuned it up new timing belt, coil wires, alternator.

But i cant sleep at night, i have engine code 16, done thousands of google searches, but to no avail. has anyone had any experience with this, any help would be great.

but some of the symptoms of this code are high idle when its first started, strong fumes while idling, thats all I know

thanks in advance.
Rob

Qld
code 16 is
fault in communicatio0ns between the engine ecu cpu and ect cpu
since ls400 have one ecu fo both im guess your ecu might be nackered
says if there are no other codes then replace ecu

if your ecu has code 16 in memory it prohibits the torque control of the ect
which peforms smooth gear shifting


i guess thats y it was cheap heheheheh
must be cheap as it has pretty hi kms

well i got it for 400 usd, kid thought it had a bad engine, got it home bearing on the water pump was seized, as far as the miles on it, the oil comes out clean whenever i change the oil and beside the code 16, car runs like a dream.

thanks for the help and a question what does nakered mean specifically, im puzzled over here in the us
