07 denali
I own a 07 yukon denali, as of late it has a performance issue. When driving up hill and trying to accelerate it feels bogged down. It doesn't fall on its face but it defiantly feels labored, until I push it through enough that it finally accelerates. This suv has just at 50,000 miles on it. Something else it has done recently is dieseling at start up. Anyone else have these symptoms?

Re: 07 denali
1) Start with a new air & fuel filter.
2) Clean the Massive Air Flow sensor with CRC MAF cleaner. 3) Also get your catalytic converters checked at a local muffler shop. If diesel effect, turn her off, and restart. |
