About a month ago my service light come on. So i took iti to the dealer. They said it was my O2 senor. I pick up my truck and it was still there. They said they replaced both of them. Now my fuel gauge is mess up too. Some time it works, but most of the time it read zero or lees than a 1/8 of a tank until I've been driving for more than 30 min's.
Also my door ajar light comes on somtimes while driving and my ABS comes on after I've been driving for a while and stop a light then take off again. Is this all the same thing cause all this or is each diff?....
