O.K., ever since I've had my cam put in, my SES light has been on. Until yesterday, every now & then it would go off for a little while. We've had cooler weather down here lately the last 2 days and my light hasn't come on unless it was in the heat of the day. All day today, it's been off. But, it only happens when its under 80-85*. Why is it doing that? Is it getting denser air and helping out my A/F ratio or something? The converter is still locking & unlocking at the wrong times and making my driving time torture. Can anyone explain this? Thanks!
