That also solved one of the two problems I had also with my 91 S10 2.8 TBI. The low temp sensor output was keeping yours and mine computer open looped or in a limp mode and as a result, it would be rough running depending upon the condition of a lot of things. This is probably the key sensor to determine which mode the computer can go into.

I had to fix this problem first than tackle the other one which was intermittent operation when hot. I found it today. One of my TBI injectors was intermittent because of a bad connection in the computer connector. I cleaned it up and squeezed the socket for a better connection. So far, it seems to be working and the truck runs as good as a new one now.
