Replying to: middleseat (Sep 07, 2006 9:30 am) Intake air temperature is one of the data points that can be read thru the data port where the scanner connects. With your problem you should have this reading checked when you have the problem during hot days.   You can do this yourself too if you want to invest a $110 or so. You can purchase a CarChip data logger. It is a small data logger that connects to the diagnostic port in your car and you can select from about 10 parameters to monitor while you drive. To look at the data you need a computer.   I bought my CarChip from AutoZone.   --Arrie--
#686 of 944 2003 Chevy Sub Squeeking Sound? by fch3 Oct 12, 2006 (5:51 am)
I have a 2003 Sub LT and it has recently been squeeking near the rear when I hit a bump. I thought maybe the shocks, any suggestions on what it might be and how much it would cost to get fixed? I'd like to go into the mechanic having an idea of what it is and how much it will cost. Thanks! Replies to this message: ahightower (Oct 12, 2006 4:52 pm)

Replying to: fch3 (Oct 12, 2006 5:51 am) I'm no expert, but it's a big vehicle and the description you gave could be just about anything. Are you sure it's coming from the outside rather than the inside? Underneath? Have you ridden in the back with someone else driving and tried to get a general idea where it's coming from?
#688 of 944 We need your help! by tidester HOST Oct 15, 2006 (10:16 pm)
Hi, everyone. As you've probably noticed, we have been trying to refine the discussions into more narrowly focussed topics. Our objective is twofold. We want to make it easier for people seeking specific information about their vehicles to find it easily and without having to wade through hundreds or thousands of postings.   To those ends, we will be shutting down the general make/model discussions and work exclusively with specific issues. This requires us to populate the make/model subsections with relevant, interesting and timely topics. Rather than having the hosts simply create boilerplate topics for each make/model, we feel that you, the owner, the make/model enthusiast and the prospective buyer can best judge what those topics should be.   You can help by adding a discussion (it's easy!) or suggesting one here.   To add a discussion, click on the last link in the "You are here" line at the top of this page. That will take you to the topic page for this make/model. Review the list of topics and click on the "Add discussion" link when you've decided what topic you'd like to add. Follow the directions and you're done! Feel free to add more than one. Just avoid duplicating existing topics and try not to make it TOO specific!   Your help and continued participation in the Forums is greatly appreciated! Thanks.
#689 of 944 Help! My Suburban is stumping the mechanic. by redsuburban Oct 16, 2006 (2:12 pm)
I have a 90 Suburban. Only 100,000 miles. Running perfectly. Had the fuel pump changed b/c we were in the gas tank for another reason. One week later stepped on the gas and a huge loss of power. Would only go about 15 to 20 miles per hour. When you would step on the gas it would rev up normally about 1/2 way to the floor then it "cuts out" and losses power. Check engine light comes on. It doesn't idle rough or run rough, just no power. This is very intermittent. It will work bad then run fine for a few miles, then bad, then fine for days then stalls completely & won't restart. We have had it in the shop numerous times. Changed fuel pump. Cat. Conv. test fine. He has changed the fuel filter, ignition module, ignition coil. Now he wants to change the EGR valve. I think he is just guessing. The check engine light is never on by the time we get it back to the shop so it is tricky to figure out. Any suggestions?Thank you.

Replying to: redsuburban (Oct 16, 2006 2:12 pm) I had almost the same problems with my 97. LOSS OF POWER. This happened about two weeks after it was towed for a new fuel pump. I bought new cam sensors, EGR, wires plugs, you name it. Turned out to be a bad new fuel pump. This time I made sure we used a DELCO FUEL PUMP.

Replying to: v8fun4u (Oct 16, 2006 3:03 pm) Everyone has told me that a bad fuel pump would not be intermittent, it would just go out. It is a pump from Napa. I'm not sure what kind they put in. Did you have major loss of power? My mechanic says, no, it's not the fuel pump. GRRRRR. Thanks.
#692 of 944 Just bought 1998 Suburban... by doceddie Oct 22, 2006 (7:58 pm)
I just bought a 1998 GMC Sub 1500 4x4 w/ auto 4x4. The lights don't come on the 2hi/auto4x4 or the 4hi/4low switch. I can here it switch into 4low in neutral and seems to go ok. But I can't tell when I'm in 2hi or auto4x4.   It has 146,000 miles and it was "Serviced" at a vo-tech place w/ no records. What work/ service would you do on it now?   Paid $5000.00   Thanks...ed Replies to this message: steve_ (Oct 24, 2006 10:18 am)

Replying to: doceddie (Oct 22, 2006 7:58 pm) The Edmunds Maintenance Guide will give you an idea of what the manufacturer recommends at various intervals (you may have to drop the "100,000" and start over with 50,000 miles).
