Hi guys. This is my first post on the forum here. I'm a hobby wrench turner, mainly working on Hondas I've owned, and a supercharged Miata that's my little money pit. I would say my knowledge is just high enough to attempt things that cost me major bucks after I screw them up, although I did replace the entire AC system in my wife's Honda Civic, from soup to nuts, so I have my moments.
I have owned, since new, a 2001 Suburban LT Autoride, 2WD, with the 5.3 liter engine. I have done a few oil changes on it myself, and changed a flat or two, but other than that I haven't messed with it at all. The problems I have had over the last 7 years are a replacement of the ABS module, replacement of the AC belt tension arm, which I did myself, a leaky window washer resevoir (bought the part, never put it on) and that's about it. It's now over 100k, and I'm getting some problems popping up.
These include:
AC making a screeching noise from time to time. I thought it was the belt tension arm, as the spring was broken, but it's an intermittent problem. Some people tell me it's the compressor bearings.
Voltage meter and RPMs fluctuating at idle, and the vehicle will stall out on occasion when making a slow tight turn, loading the power steering pump (my guess), or when coasting into a parking lot while making a turn. I've gotten some advice from a friend who is a master tech, but he's 600 miles away and cannot see the car. He says it may be the front O2 sensors needing replacement, or that the intake manifold gasket may need replacing. He sent me detailed instructions on replacing thegasket, and it doesn't look like something I want to attempt on my own. I'm also wondering, from my experience working on my Miata, if the MAP or MAF sensor may be clogged, whichever this uses.
Before I start tackling the other stuff, I'm trying to replace the plugs, and I am stumped by the aluminum sleeves that bar access to the plugs themselves. Do they screw off, or do I need to use more muscle? The owner's manual doesn't even mention how to remove the plugs, so I'm stuck here.
Next I will be replacing both O2 sensors, so the location of those would be helpful.
Thanks ahead of time for the help.
