CEL for system too lean need help...
i just got a check engine light for code 10701 - system too lean on bank 1. this code came up last year and after it was cleared, never returned. however, this past week, while driving in a snow storm, the CEL came on reading this code. the car seems to be driving fine, no noticeable difference. i had the code checked and cleared and it did not come back for a day. Today, while on a drive to the mountains to ski, the CEL came back on and i assume its the same code. should i be worried? what could be the cause of this code and how serious of an issue is this? this CEL seems only to come on during cold drives or changes in elevation above sea level. i had an oil change done 1800 miles ago and spark plugs about 8000 miles ago. thanks so much in advance!!!
