Hey guys,
Here's the scoop. '95 Blazer, 172,000, newish cap, rotor, plugs, and wires. I put new top end gaskets on it and messed up the timing, bad! My uncle helped me get it right, and we found that the plugs were all fouled out, so we swapped them out with another set and it ran fine. One day I went to move it and the SES light came on. I let it run as I went to get my code reader and came back and smelt something burning, I looked underneath and the cat. conv. was cherry red.
I shut it down to so it would cool down, ended up waiting until the next morning just to be safe. I did find that the tps connector had a wire that was loose from the actual connector, and I still have to erase the codes to see if they come back on.
I took the plugs out and took a fine wire brush and cleaned all 6 of them. I noticed that the driver side plugs were black and the pass. sides were not.
What do you guys think would be causing this??


Thanks in advance.

 

Have you read through Kyle's write-ups on these codes in the Diagnostic Trouble Codes section?
