i guess this would be an update...

now that i know what open loop and closed loop are, i can answer the earlier question of my problem cropping up. the erratic idle was only in closed loop, as was the sputtering and hesitating. The knock sensor was pulling as much as 15 degrees of timing when it was doing this, according to a GM Tech2 scanner. I was thinking today, i wasn't having all of these problems until i replaced my timing cover seals, water pump and opti. i'm wondering..as silly as this sounds, could teflon tape on the CTS in the water pump be the culprit? it's the only thing that's different...i replaced the plugs and wires, today is the fuel filter and O2s...but if it's only hapening when the car warms up, i'm thinking maybe i goofed in doint that?

opinions?
