1998 GMC Sonoma Question: Keep getting p0172 code on longer trips

I have changed the o2 sensor and the tps that was acting up but I still get the code on longer trips. I have clean the throttle body with spray and don't believe there is a MAF sensor on this motor. The truck runs great but the fuel economy is lower than it should be. Starting to scratch my head! -
