Engine Cooling problem
2006 Hummer H3 V8 Four Wheel Drive Automatic 118000 miles
My 06 Hummer H3 suddenly began missing running extremely roughly especially when the AC is on. I did get some suspicious fuel so have some concern that it is bad fuel in the system. The engine light is coming on. What should I do? Fuel filter? Injectors? Plugs? HELP? Thanks in advance.
