#1632 of 1973 My 1998 Safari is setting Code 175
Sep 09, 2007 (5:12 pm)
I have a 1998 GMC Safari that started setting off code 175 (right bank is running rich) a while back. My mechanic thought that I needed to replace the O2 sensor. I replaced all 3 ($128 x 3 + sales tax) and it did not set codes for a few weeks. The code is back again and I don't trust my mechanic to do further diagnostic work. I also don't trust most repair shops or dealerships but I am afraid that I will have to break down and take it in. Can anyone here recommend a repair shop or dealership in Houston, TX.

I am having pretty much the same problems with my 92 safari awd. It will start and run fine but when you drive it stalls out. It then needs a bit of time to cool down.
Iv had a pressure test on the fuel pump, new fuel filter, new plugs, wires, coil, ignition modual, distriutor and rotor, but nothing has helped. Does any one have any ideas that could point me in the right direction please???

I took my Safari in to an independent shop and they scanned it and said there was nothing wrong that it would set the code and then remove them within a few minutes, that it was an intermitent problem. Your problem is different than mine, I have no stalling problem and you have an OBD I emissions system and I have an OBD II system which operate differently. You need to take it to someone that can provoke the symptons and then fix it.

My 1995 with 260000 did that also and one thing to check out is the coolant temp sensor if yours had one. The reason I say this is because these vehicles being general motors also I find have "general parts" from the parts bin at build time so I sometiomes don't find the part on my vehicle.
Here is my problem also. No brake lights when peddle is pushed. I replaced the brake switch and still no brake lights. I read on another site about the "Multi-Function switch" needing to be replaced but what is confusing to me is the Haynes manual descibes replacing the "MultiFunction switch lever".Is this attached to the MF(this is about how I feel about this van at the moment and why it is for sale ) switch? This makes some sense because when I press the brakes with the blinker on the radio blinks but the lights don't blink on the driver side. Also the high mount(3rd) brake light goes out but when the right turn signal is selected the 3rd light come on. So some "multi functions are out of whack it seems.
This van was broken down and I was at teh end of my ropoe and paid a guy $200 and was told he "wired it up right". Its running but has no brake lights. I am about to go back to him but would like to know if anyone has any ideas about the MF switch; its location and removal/replacement?
#1636 of 1973 Astro 2001 - Rear End Thump
Sep 18, 2007 (4:27 pm)
I have a 2001 Chevy Astro 2wd w/ 55,300 miles
I recently had the rear end replaced due to a bad diff (as per mechanic). There was a constant noise coming from the rear when I accelerated. Now I'm getting a thumping sound from the rear when I release the brake after stopping. I've been back and forth w/ the mechanic as he does not seem to know what the problem is. First he thought and still thinks its the brakes not releasing properly. I think it may be a bad rear end from the salvage.
Can anyone provide guidance as it's getting riduculous going back and forth to the mechanic.

Actually, from the sounds of things, your rear brake isn't releasing. And although you didn't specify a side, I'll tell you I'm 98% sure it's the passenger side rear. And you may be able to get your mechanic to fix it, but it will probably come back. Not sure why, but believe me, after owning GM cars since 1984, I haven't really found any (other than the smaller cars cavalier, sunbird, etc.) that didn't have this problem. I have 2 1994 Astros and a 1995 Safari and guess what, they all have the same problem. Not your rear end though, not in my opinion.

Thanks for the feedback.
What would the mechanic need to do to fix this problem?
The issue I have is that I never had this problem before the rear was changed. Seems to me now that one things goes in the Astro everything else will start going. Is it worth the hassle and the money? I'm betting you've had the same other issues that I've been experiencing & reading about with the astro's: door locks not working, driver side windows getting stuck, abs light & brake light staying on, etc.....

If your speaking about the thumping problem, no because the mechanic still has not found what the problem is (after too many return visits back to him) and I'm trying to get some feedback as to how it can be fixed.
The problem with mine is that it doesn't happen automatically. The van needs to be driven awhile before it starts acting up, especially in bumper to bumper traffic or if I'm at a light and I release the brake.
Don't know if I want to keep investing in the vehicle if something else just keeps on going.

Yes. One can easily remove the "factory mush" rear suspension. One method is to install Air Bags (like the ride right system) and the other method is to install Timbrens. If wondering, Timbrens are like air bags without air inside them.
And if you want, you can also install Timbrens on the front - if you want to reduce suspension depth and ease of movement on its front. But installing Timbrens on the rear is a great first step.
With Timbrens, your van's unloaded ride comfort is NOT changed. However, your van's rear sag (from loaded weight of onboard cargo or trailer tonque weight) is removed. And the best part is, the more downward pressure on the Timbrens, the more the Timbrens work. If wondering, I have Timbrens (2,000 lbs verison) on the rear of my 2001 Safari van, and don't leave home without them. Seriously, best suspension improvement product I ever bought for my van. I'd buy it again - without hesitation. For more details, surf:
