Hello all. I've had this "too lean" error code for months now and haven't been able to find the cause of the problem. It is affecting my fuel economy and driving me crazy trying to resolve it.
Here's what I've done so far:
1. The spark plugs and leads were replaced approx 12 months ago.
2. Replaced the distribution cap and rotor 6 months ago.
3. Put in a new air filter 6 months ago.
4. Replaced CCV valves and pipes 2 months ago.
5. Replaced upstream and downstream oxygen sensors 2 months ago.
6. Replaced ignition coil 2 months ago.
7. Replaced TPS and installed throttle body spacer 2 months ago.
Finally put it down to an air leak because I had cracked exhaust headers so I've installed extractors only to get the same P0101 error code again!
AAAAARRRRHHHH!!!
I don't think it's the injectors because I mainly run on LPG and get the P0171 code on both petrol and LPG. I'm not sure but it might only come on after a certain speed (???) because I can clear the code and drive around the local area and not see the code reappear until I've driven longer distances (at a higher speed).
Any suggestions?
