I am currently having problems with my 2002 Chevy Tahoe with a lean bank 2 code, P0174/P0171. I have cleaned the MAF sensor, changed the fuel filter, regulator and fuel pump/module because the fuel pressure was very low. Now, my fuel pressure is reading the proper 60 psi as required by the maintenance manual. I have checked all the vacuum lines and hoses to include intake gaskets as other forums have suggested-no leaks were noted. The vehicle now starts and runs great; but, every-now-and-then it does not want to start. The check engine light does not come back on but I am still having the intermittent starting problem. What else could this be before I start looking at fuel injectors?
