Tahoe issue??

[RidgeRunner]

Not very well Aussie, 2001 Tahoe 2WD 5.3L here, wife's wheels. Poor girl it is asking for another change of engine oil, radiator is leaking, then I went to drive it and it feels like the shock on the right rear is broke. I forget the miles around 95,000 ? The Service Engine Soon light stays lit all the time. Some odd Computer Code that is saying their is a problem with the computer. Runs and drives like a top. The light has been on so long I am surprised it hasn't burnt out. So I dropped it off at the repair shop next door. Now if I could get the seat re-upholstered while it is down I would be a hero..
BTW I started using Mobil One 5-30 Synthetic at around 40,000 miles. Then I switched back to regular motor oil at around 85,000 miles. No sign of leaks or burning it out the tailpipe but she now uses 1 Quart in between oil changes (3,500 to 4,000 miles.) Valve stem seals maybe..

Get me the code number, or swing it by as I have an ECM for it sitting on the shelf. I can flash that ECM to shut codes and such off, but I don't have all of the stuff here to do custom tunes for gassers(I don't have the money to spend on a wideband O2 sensor that I might use once every 2 years).

I may do that after fixing some of the other issues Ferm. If you were only closer you would have the entire job.
I think the plan is to keep it, I may need to upgrade the radio too. The sub isn't working and the speakers in front sound blown.

Mine is running like a top!! Except at start up in the morning, I have cleaned the throttle body but think it needs to be done again to be sure we got it all, as it did help alot!!
I have a few codes and have talked to Therm about them and it seems the intake gasket might be going?? I am going to test it this week and see what I come up with? If it is, CB has stated he can help and we will get it done, I have watched a youtube on it and besides all the crap that has to come off it looks pretty simple?
But I have been very happy with it so far, and will get her right!

Sounds good MJ. Really they are good vehicles. Even with little things that need repair I would highly recommend one to anyone looking for a full size SUV.

if your engine light is staying on then you need to find out what sensor stop working or it could be out of range do a self diaonotic test fix the problems and then go from there---i didnt relize the engine light was staying on

He's already told me what the codes were, and all 4 point to an intake leak which is a semi common issue for the early LS engines up north(don't know why we don't see much of it down here in the south, but up north they seem to go out fairly often, maybe the cold up there cracks the rubber).

As some know CB and I replaced the intake gaskets a couple of weeks ago. Well since then it has been running like $hit! Ferm said it might clean up after a few days as the computer had to relearn, no deal!
We had a issue with the drivers side injectors not seating good when reinstalled and after careful thought CB and I had the same thought, it was that as the problem. So the first chance CB and I had was today to look at it, took the intake off again and lubed up the O rings on the injectors and put them back in, but still was having a problem with the drivers side? Come to find out we had the mounting bracket on the wrong way after we fixd that they went right in with out problems!! Then remounted the intake, turned the key and zoooom it was perfect!! went for a long ride to do a few things and it was perfect the whole time!!
Now just have to do the Brakes,and Pitman arm and she will be perfect! Thanks CB for all your help!!
