R33V3S

I'm learning that it will, that's why I've tried to cover my basis with all the simple maintenance that needed to be done anyway. It might just be time to hand it over to a mechanic and let them sort all the issues out, while I was looking tonight I found the fuse box wasn't grounded and it had several blown fuses. Any chance you would know why I can sometimes see more settings on my dash cluster than other times, it's like the settings disappear.

I bought a used 2008 silverado 1500 4x4 extended cab and have been fixing all the issues it has. I just can't seem to track down why it has a random misfire and some of the electrical issues. I have replace spark plugs, plug wires, ignition coil packs, mass airflow sensor, cleaned the throttle body, replaced the 02 sensors, had the injectors tested. the other issue is that it only displays the trans temp, mileage, and trip mileage. If anyone has an idea of anything else to try I need the help
