#700 of 745 2001 Tahoe Rough Idle/Skip After New Plugs and Wires
Aug 18, 2011 (10:32 am)
Sorry if this has been asked and resolved before, but I'm new to this forum and have run out of ideas.
I have a 2001 Tahoe 5.3 2wd that has 160000 on it. I replaced the plugs and wires just for general maintenance and tune up, and now it wants to skip/idle rough at low speeds or while sitting still...what gives? I replaced the plugs with AC Delco Iridium pre-gapped at .040. Also put on new wires. My truck wasn't skipping before so it has to do with plugs/wires right? I rechecked everything, even put new wires on for a second time just to make sure they werent bad, and still no solution. I'm out of ideas...please help.
#702 of 745 2007 Chevy Tahoe - Check Engine
Sep 19, 2011 (10:52 am)
On Saturday, as I was driving on the interstate, my Check Engine light came on. I couldn't think of anything that would cause this at the time. The car was acting fine, and while I'm getting close on the oil change, the Tahoe is equipped with an oil change reminder as well (which has not yet shown up), so I was assuming this was not the case.
Fast forward to this morning, I get into the parking deck at work, and as I'm rounding the corners to climb from level to level, my car starts dragging as if I had a flat tire (though this was not the case). So I struggled to actually make the turns all the way up, my rear tires are squealing the whole way and I finally get it into a parking space.
I hop out, take a look around, no flat tire or visible impedance in the axles or anything, so I decide to give it another drive to see what happens. As I pull out of the spot, there is a loud POP underneath the vehicle. It sounded as if something was stuck somewhere and was jarred loose. Anyways, the steering loosens up, everything's back to normal....AND my check engine light goes off.
Has anybody else seen this happen before? Any experts out there have any ideas as to what it could be attributable to? I realize I should probably have the diagnostics run on it, but I'm also trying to avoid unnecessary expenditures these days.
Any intel would be greatly appreciated.

I just took my 2007 GMC Yukon XL to the dealership today for a clicking sound that happens once in a while. They said it was the camshaft and lifter and if fixed would run around $4000 or replace the engine for $6000. What did you end up doing? Mine has 70,000 miles and is out of warranty.
#704 of 745 Front end rattle
Nov 08, 2011 (1:52 pm)
I have a 2005 Tahoe I bought used in 2010 from a local auto dealer. From day one I noticed a rattle like noise from the front end. This noise seems to only happen when the road is uneven or has bumps. It sounds like metal knocking on metal. I have had a complete service from a Chevy dealer and they noted nothing wrong or out of place. This rattle is constant when driving on rough roads no matter if I am driving straight or making turns. I looked through the forums but could not find anyone who has the same issue. If any one knows what this is please help. The dealer was no help and a local repair shops can hear it but dont know what it is cause nothing is loose when they look under the car. Also my other issue is my fuel gauge shows inaccurate fuel levels. I can fill my car up and then it read empty with warning light and sound. After a few minutes it will read correctly. At other times it will read I have more fuel than I have or when driving just drops to empty. Anyone know whats up with this?

I believe the camshaft/engine is part of the 100K Powertrain warranty.

Your front rattle is most likely the upper control arm bushings. Every thing will appear to be "tight" but it really isn't. You may be able to see the wear by opening the hood and looking where the control arm attaches to the frame. The only "real" way to tell is to relieve the spring presser and if they are "bad", it will rattle like a bolt in a tin can. I would suggest that you take it to a good Mechanic you trust and ask him to check the control arm bushings, if he is any good, he should find it right away. Good luck.
As for your fuel gauge issue, it could be the sending unit located in the gas tank or the gauge itself, I've seen both. Tell you Mechanic about it and he should be able to do some tests to isolate the problem. Hope this helps and

I ran a 2001 Yukon 421,000 miles and never had any issues like this but there are two potential culprits form my experience. First is electrical. Remember that each cylinder on that engine has an individual coil providing the voltage to each plug. Unlike the old systems with a common coil. If you have a bad coil on one cylinder this can cause this. I would pull each plug to see if one or more are noticeable different or possibly sooted up more than the others. Another possible cause is that GM had issues on some cams that caused them to prematurely wear the lobes off. If the valves are not oppening correctly to let in the gas or let out exhaust you will have performance issues and possibly what feel like a cylinder miss.
Hope this helps.
#709 of 745 Cost to own new style Tahoe & Yukon
Nov 23, 2011 (10:09 am)
I normally do not do a lot of complaining about cars but am frustrated enough to let you know what I think of the new Chevy and Gm designed Tahoe, Yukon line of trucks. I have been a loyal GM customer for a long time and last year traded in my 2001 Yukon with 421,000 miles on it after encountering a light post in a parking lot requiring repair. Thought it was telling me it was tired. Actually it was bomb proof except for their poorly designed fuel pump issues.
On to my 2007 Tahoe purchased with 43,000 miles, a virtual baby to me. I do approximately 45-55k miles per year and almost all is highway driving. Chevy replaced one front spindle bearing around 75k miles under warranty then a second spindle bearing the other side around 85,000 miles. All at their cost great for me right? Not so since these two components actually cupped the insides of all of my tires which were brand new so essentially wore them out to an unsafe situation prematurely. Pretty expensive when you look at 18" tires at close to 200.00 each. I just mounted 4 Blizzack snows before we were hit with that freak snow storm 4 weeks ago and last week saw the left front tire inside area almost worn smooth. Again almost 200.00 per tire. Now at 101,000 miles I'm told the upper ball joints are getting lose and need another 800.00 worth of repairs. Chevy this is disappointing and reflects on their light weight front end and their outsourcing to the lowest priced parts. This truck has had more repairs to the front end in 100,000 miles that my older Yukon has in 400,000. By the way it was again our of alignment another testimony to poor engineering and cheap parts. My 01 Yukon had 3 or 4 alignments in the 400,000 miles and not once did it cup tires or have any issues in the front end. I have to say Government Motors is making the choice of my next truck easy and it will not be built by them. This is not a truck any longer and if you plan on doing any heavy duty driving or have poor roads buyer beware it will cost you a fortune to own. For a vehicle that costs $55,000 new this should be an embarrassment to GM but knowing them it is not. At least we are not hearing claims "Like a Rock" on their commercials any longer. Think that in itself is a message.
