Warm weather and P0171 corelatio

[Hazara]

Hello everybody,

I am back after over six months to nearly a year with P0171 problem. During cold weather traveling on motors on consistent speed of 70-80 had no problem, but with warm/hot weather traveling on motorway after 40 miles the P0171 power train system too lean shows up.

Any idea, why?

Any remedies?

Check for airleaks around the exhaust manifold.

Thanks,

If its a leak issue it come in normal driving as well. But it shows up only driving on motorways in hot/warm weather. In late autumn and winter lts not there even driving 100 miles on motorways non stop, but in hot/warm as in june/july after 40-50 miles on motorway it show up again.

For what its worth I have had this before in the warm weather and it turned out to be a faulty 2nd Lambda, I also seem to remember seeing a thread on here about it possibly being the MAF.
