'88 Blazer better, but not fixed.

Hey everyone,

I drive the Blazer home tonight, and it was 80% better. No black smoke, no real hesisataion. Would stall at idle (cold or warm) but drove home okay.

No ECM codes, I think there is a slight exahaust leak on the pass. side. Don't know if that would affect anything (other than emissions ;))

Will replace the 02 tomorrow A.M. -- hope this is the problem. Otherwise I might pickup a new AIC(Air Idle Control) valve -- this one is old and I may have hit it with carb cleaner -- maybe it's dead?)

Talk to you soon -- I WANT MY TRUCK BACK AND I WON'T GIVE UP -- famous last words!!!

Have you ever replaced these O2 sensors? How long have you had this vehicle? I'm not familiar with your history of posts here in the group, sorry. You don't have to reiterate for me, I have an 88 S-10, just rebuilt 2.8V6. Anyway, if you replace the O2 sensor and it doesn't come out easily, [you'll need a special deep socket], you can easily strip the threads. Which means you will either have to get a new exhaust pipe or weld a nut onto the top of the pipe. None of that is easy. Be sure to wire the thing far away from the exhaust pipe as you can get it so it doesn't get burnt and defeat the purpose. Why do you want to change the O2 sensor anyway?

Ok, now I see the thread where you posted before. Looks like you've done some major work yourself, and I noted that you said you hadn't checked compression yet. Have you now? You've had the rig for a while I take it from some of your other comments, but you don't mention when it started to act up. I haven't been here in a while, but I sympathize cause mine cost me a ton of money and finding the right guy. Have you been inside the block? I had a dumb ass tell me my compression was alright. Not like new but all cylinders were about the same he said and not low. Except the cam shaft proved to be trashed by someone else! The first guy charged me a total of $900.00. He did get my air conditioner working by just replacing the plug to it! And never charged me for that. Chev dealer had told me previous that I'd have to have the entire compressor replaced! Oh my! Really? Same guys that told me when my speedo was f'd up that I'd have to have a whole new dash board. Plastic gears in the transfer case fixed it. Hope you get it done, but I'd start looking back on the inside and forget the sensors and computer for now. Or like I did, spend 4K and get nowhere.
