Hello,
The engine on my P38 (petrol, 4.0 litre, Bosh) is not running correctly. Normal pressing of the accelerator usually slows the car. By pressing very slowly, and gently I can increase speed. Flooring the pedal also increases speed.
Hills, even gentle inclines, are a struggle.
Error codes are (after clearing stored errors and a short drive):
PO 134 - Lambda sensor upstream catalyst bank 1 drive cycle C, signal missing
P 1000 - Lambda sensor upstream catalyst bank 2 drive cycle C, signal missing.
Is it time to replace the oxygen sensors or, because a signal from both banks is missing, could it be something else?
Many thanks,
Bertie
