03 suburban electric problem
Hi, I have a 03 suburban, the emission light was on and the speedometerwas not working. My mechanic replaced the bank 1 sensor 2 and the speed sensor, this worked for about twenty miles. I returned and he replaced the 02 sensor with a oem one, but that did not work either. the light came right back on. The speedometer works sometimes on the initial start and go, but after about 30 miles there is nothing or it is way off. Last week while driving none of the dash lights worked, with the exception of theemission light. Not sure if it is related but the gas guageindicates that I getabout 300 miles on the first half but the second half goes very quickly, very quickly. Ran out twice. Please help!!
