Mine went bad Monday. I started it and it ran fine. I went to Home Depot and picked up a few things and when I came out it would not start. Just cranked and cranked. I was just ready to call a tow when I decided to crack a injector line to see if it was getting fuel. Fuel was under pressure so I ruled that out. However, when I tried to crank it again it sputtered and started to act as if it was flooded. or out of gas. I knew it had gas so I kept trying. it finnaly started and sputtered for about a minut before it smoothed out. It then drove home with no problem. At home I shut it down and tried to start it again. Same problem. But it did start sooner. Only now, when I drove it, it did not want to rev quickly. It would try to stall and sputter when I pushed the pedal down quickly. I will also check those hoses today. I also have no idea how to check the O2 sensor.
