Question about 2003 GMC Yukon Denali
Our Denali is misfiring. We have taken it to 2 mechanics and they cannot find the problem can anyone help?
It could be alot of things...you could start by routine maintnence( new spark plugs, spark plug wires, air filter, oil change, the in line fuel filter) also take into consideration what kind of gas you are using...i know it sucks spending $100 a week in gas with your AWD 6.0 liter V-8...but if ur not running premium it could very well be your problem. I have also heard of the denali's having oxygen sensor issues...is it throwing a check engine code?
