When I first bought my yukon, I installed a Air raid Jr intake, put my stock MAF up, and stuck a MAF in the truck that I removed the screen from. Now nearly 2 years later I had pretty much forgotten about the MAF. My check engine light has been on since the first of this year, everytime, it gives a different trouble code, all relating to 02 sensors. So I asked around, and even asked a few of you guys on here about my problems. Well, this morning flossinon_24s mentioned that I should check my MAF, and I thought I have another I can stick in, then I remeber pulling the screen out. I swapped the original MAF back in and went for a test drive. The engine light is still on, however, the truck is idling normal and not at 400 rpm; when I left off the gas at a cruise, the engine stays at 1000 rpms and lets the truck roll. I even have my bottom end back, something I had forgotten this truck even had; it will spin the tires on rough pavement. While I was out, I popped out the camera phone and took a video. I thought I would share.

There is a short in the wiring in the seat, it gives the air bag light. I am going to replace the seat when I find one. Sorry for the one part where the camera is all over, I am shifting down to first to turn the traction control off. When I get a chance to take it out on the interstate I will see if I can really throw the girl open for you.


No speed demon here, however this is a 5500 lb truck (verified on truck scales) , and I will put a trailer behind it to prove it pulls just as hard with a trailer, gotta love the 4.11's. I definitely see potential with a computer tune. My Dad will be driving the truck for the next little bit so guess he will get to enjoy the new found power.

on myspace, youtube is doing maintnence.

Looks like about 9 seconds 0-60 on the first launch and I wasn't at full throttle, it also seemed to shift rather quick. I start at .03 and reach 60 at .12. The first take off I am watching traffic, the second is in gravel and I am trying not to throw it on people in the parking lot, the third I am clear, but cops sit around that bend so I couldn't be speeding.

I love the rapping when I let off the gas. It used to do it alot more before replacing the MAF. But what do you expect when drops to 450 rpm when I let off.

And now on youtube.com
