05' Silverado ABS/Airbag/speedo help
i have an 05 silverado crew. 5.3 Z71 4wd with 175k miles. i drive it every day on average of about 1000 miles a week. around a year ago i had the service brake system and abs light come on while driving down the interstate 75-85 mph. it would come on every now and then only at higher speed and then turn off minutes later or untill i slowed down. this is on and off for a year now. last month at 50mph my service engine soon light turns on, brake system light turns on, and airbag light turned on all in a row at one time. advance auto says engine light is oxygen sensor- front right. air bag light is rarely on and off, but brake system msg comes on all the time 70-80 mph. this weekend i went out of town, brake light comes on again and speedometer goes crazy, fastly fluctuating-showing between 65-80 up and down, up and down, although maintaining a speed of around 75. it lasts a few seconds or untill i reduce speed to about 70 and it will be back to normal. im thinking speed sensor on the speedo, but what about the brake msg, and that ghostly airbag light????? please help!!!!
