97 FZJ 80, European spec., delivered to Finland, no OBD2, 1FZ with 360 000 km on the clock.
for the last 2000 km (starting in the dunes of Grand Erg Oriental/Sahara desert) the CEL came on intermittendly. When trying to get a code with the paperclip method: continuous blinking and after restart light was off.
Then some loss of power again intermittendly.
After retorquing the exhaust flange after the Catalysator: everything gone for 500 km. After the ferry over the mediterranian it came on again, after a restart complete normal behaviour for 600 km.
No oil comsumption, no coolant loss, temperatures never over 85°C/185°F.
I am inclined to blame the O2 Sensor getting sometimes air enriched exhaust fumes.
Any ideas, where to start the troubleshooting?
Thank you very much!
Regards Simon
