I just had my O2's, which were dead, and mt ECT replaced. I also put the stock T-stat back in the car. Suddenly my gas mileage appears to have taken a dump. I replaced these parts to fix this issue. Anyway, my question is this: does the computer on these cars take time to 're-learn' all these changes, and how long should it take?

yea it does take time to relearn, just unhook the negative battery cable for 10 minutes or so and it should relearn

Well, that was the thing. I replaced the sensors, which were only a year old, and now the mileage tanked even worse. I'll disconnect the battery later when I have a chance, thanks.
