#3238 of 3259 PLEASE HELP ! 2005 YUKON 43000 miles by paulkc Dec 25, 2008 (11:43 am)
My Yukon's check engine light is on and it feels like its going to die at stoplights. I had a buddy check the codes and 3 popped up: too lean, multiple misfires and low voltage. BUT the problem is inconsisent! It will sometimes run okay and theres no problems when idling in Park except check engine light is still on. Weather doesn't seem to be a concern, as it did it in 1 degree weather and also 38 degree weather, (crazy Kansas weather!)   I have a new battery in it, (less than 1 month), and dealership advised alternator was fine when they put it in.   Described problem to dealership and they think it might be an intake manifold gasket shrinking up in the cold...BUT...it was fineuntil a few days ago when it had sat in the 1 degree cold all night. It ran for 30 minutes around town then when I strarted it up again, it started this problem. The plugs are iridium and should be good til 100k miles.   Any ideas are greatly appreciated, as I dont have much $$$ to pay somone for hours of poking around. Thanks!

Replying to: paulkc (Dec 25, 2008 11:43 am) Check engine light is usually associated with emissions. In your situation it seems like it could be the MAF sensor as it leans or enriches the amount of fuel to air mixture based on air intake temperature. I would find it unusual as the MAF isn't known to fail on the Yukon, but there are instances where I've seen them in need of replacement. Replies to this message: paulkc (Jan 03, 2009 3:05 pm)

Replying to: obyone (Dec 25, 2008 1:17 pm) HA! At first the dealership said it was fuel injectors which had fouled up. THEN after making it 100 yards out of the dealership, it acted up again, so after another 24 hours, they advised it was the catalytic converter, which was causing the back pressure problem and apparently fouling up everything else. Hopefully they will test drive it this time, cuz I will have had this rental car for almost 10 days! Thanks for the info. Paul

I have recently had both my front heated seats stop working on me. Neither of the lights come on, I am thinking its a relay, but not sure which one? I was looking last night and there are multiple clusters, Can anyone help?  Also I have an obnoxious rattle/squeak in my passenger side dash? sounds like it is deep into the dash, any thoughts?  thanks for your help!~

Replying to: obyone (Feb 28, 2006 9:40 pm) I need to raise the front a little how do I adjust the torsion bar? Replies to this message: rsht (Feb 07, 2009 11:23 am)

Replying to: fongerelli (Feb 04, 2009 10:24 am) I am not absolutely sure about your particular year model, however, the torsion bar adjustment is done by turning the torsion bar adjustment bolt (follow each torsion bar from the lower control arm toward the mid section of the vehicle, you should find the adjustment bolt at about the section below/behind the driver seat for the left side and opposite for right) . It will be much easier to turn each bolt if you jack up the front end (you can do this one side at a time) by the frame to take the weight off of the front suspension. Find a reference point on each side and take initial measurements before making the adjustment; measure each side of the SUV again after adjustment to make sure both sides were raised to the same height. You may need to have the alignment checked after adjusting the torsion bars...
#3244 of 3259 torsion bar adjustment on a 2000 Yukon by fongerelli Feb 07, 2009 (3:50 pm)
Thanks for all the advice and it worked! It raised the front end about an inch which gave me more room for my 35 x 12.50 x 16.5" mud tires! I'm still hitting the windshield tank when I turn hard right though. I shaved as much as possible without any leakage. I might have to move it foward or up or re-position it elsewhere? Any thoughts on this anyone?
#3245 of 3259 re-mounting the auto ride sensors on 00 Yukon? by fongerelli Feb 08, 2009 (3:42 pm)
Has anyone ever repositioned the sensors on the Yukon to make it higher? I would like to try this and is it safe? Please advise anyone. Replies to this message: rsht (Feb 11, 2009 7:01 am)

Replying to: fongerelli (Feb 08, 2009 3:42 pm) I take it that you are talking about the Electronic Air-shock/Auto-leveling system? If yes, I have helped my friend with his Suburban where we only re-adjusted the linkage to each position sensor to raise the rear end higher by just about an inch. If I recall correctly, we only extended the link rod by about half a turn. You may want to double check on your particular model if the link rod needs to be extended or shortened to raise/lower the ride height... By the way, I recall seeing some sort of acceptable range limit/specification in doing this kind of adjustments, you probably can find such information in one of the GM Service Manuals.
#3247 of 3259 electronic auto ride by fongerelli Feb 11, 2009 (1:30 pm)
thanks a lot for the infor. Have you tried adjusting the torsion bar? That brought it about an inch but it has some side affects, at 45 the stering wheel shakes (and its not the balance on the wheels) Which way to turn them? I see them and just wanted to know exactly which rod to turn, I turn it shorter or towards the body or clockwise? Please advise. Replies to this message: rsht (Feb 12, 2009 8:27 am)
