p0171 code what is the fix?

Question

Hi Reynaldo,

As you mentioned I checked every possible vaccum leak. Could not find anything two vaccume connectors looks like little bit week I changed those. But funny thing that when I cleared 'P0171' after starting engine for the first time start error don't come on, after engine is hot starts hesitate and some time shuts off. immediately I start the engine for second time in about two to three minutes error is back. Any ideas. Thanks again.

EGR okay,hows the PCV valve, when it acts up disconnect the MAF (Mass air flow ) it the idle quality improves that where the problem resides
