Vannin' Home Forums Chevy Troubleshooting Code 32 Code 44 on 92 Chevy G20?

Ok so I searched through about 15 pages to see if I could read a duplicate of the problem I am having. No luck. Close though.
I just drove my van down to the Florida Keys. When I started service light came on, then went off. I probably drove 150 miles before it came on again. I was on the highway, light came on and it died at about 65mph..luckily right by service station. it did start back up. I let it set. It reset and was driving fine. Awhile later light comes on, and pretty much have to floor it to keep up to speed 55-60mph. This was how the rest of the trip went.
After my arrival I purchased a New O2 sensor and installed. No issues while driving in Key West. Drove it back the 300 and some miles. I got within 20 miles and light comes back on, and mashing down of the gas pedal to keep it running at 55. Code check says 32 and 44.

The odd thing is that it ran all the way back from key West with no service light coming on, or no other issue. I am thinking that the plug that the O2 sensor plugs into maybe the problem. It doesnt actually lock into place. I have not checked the EGR, which the other code.

Anybody have this issue before?

Change fuel pump relay switch, cost about $10.00 in any auto part store. Just about 5 min to change. Hope this help.

Yupp Did that right before I left on vacation.
