RUNNING ROUGH

2001 Chevrolet Blazer

I just bought a 2001 Blazer and it started acting up the day after. I was at a stop and when I pressed the gas pedal nothing was happening, then it was revving up and down until the service engine light came on. I checked the guages and all seemed normal so I looked under the hood for any visual problems, still nothing. I started it and it ran fine the rest of the way home. My friend did a diagnostic test and it came up with 0300 random misfire, and 0150 O2 sensor. It was running fine again and then last night it ran like garbage again, where I would step on the gas and nothing would happen. I felt a clicking when I had my foot on the pedal and it would stop after it registered that it was getting gas, but it eventually died in the middle of an intersection. I drove it home and didn't drive it until today where it ran fine again. I was thinking that it was the fuel pump, but before spending the money for that I wanted to get other opinions.

If it was me I'll check the fuel pressure for a start to find out what's happening with the pumper.

Random Misfire normally is an indication of vacuum lead and bad gasolina.

EGR!

Would this explain the clicking under the gas pedal?
