Engine Performance problem
2006 Hummer H2 V8 All Wheel Drive Automatic 25000 miles
hi, I have 2006 hummer h2 and only 25000 miles. Engine running rough for more than a year. Went to the dealer he says there is no any code. Can anybody help to find the problem. Its not running smooth. And how can I find out if there is problem with the exhaust valve. Thanks
