Hey there! My 90' K1500 350 TBI has suddenly been acting up when you go to give it gas or put it under load as in going up a hill. It just loses a lot of power and sputters around. My first thought was fuel pump. It is idling fine. It has been having a slower or prolonged crank to start. It was running smooth until I took it for a new set of tires (go figure). I pulled the codes and got 32, 43, & 44. I unplugged the ERG line and saw no difference in performance. My next planned steps are to test the fuel pressure and maybe replace the MAP sensor. Any other tips tricks or other things I can try b4 I start ordering up replacement parts and praying?
