Hey guys,
Any of the coffee shop crowd have an OBD 2 scanner for my 04 Yukon Denali?
Once a year when I pull on the hiway & accelerate Hard I get a check engine. It goes away after a couple starts for another year but am curious what it is?
Always under Hard Accelleration & usually when towing but yesterday I got it with an empty truck but I went from 40-125 pretty quick to get into the traffic.
Not in the mood to drop $200 for a decent one. I will gladly pay for the use of it for 5 mins!! :yup: :cheers:

Thanks Dave!
Think its a dirty air filter cuz when I removed it the code went away within a minute. The guage shows 40% dirty so under heavy load not enuf air flow. Time for a new one!

Clean your MAF while you are in there. Use a q-tip and be gentle with the wires.

Mike sounds like a plan. The truck goes to St. Catharines every single weekend (since Christmas) so Wendy & her sister can be with their Mom.
It's getting used a lot compared to my 1/4 tank a month! :yup:

I'm amazed that after 4 years the brake pads are still 50% when my Windstar needed them yearly!!
