that sucks dude, good thing you have another vehicle. right now my heads are being put back on. if you had bean running rich before the repairs alot can get fouled up.

You replaced the intake manifold and all gaskets right, dumb question but my truck threw those same codes plus o2 sensor 1 & 2 lean.

Nvm it looks like you did. My bad.

When I did the initial repair, I replaced all of the plugs, the wires, distributor cap, rotor button, and the knock sensor. I didn't replace any of the O2 sensors though. I bit the bullet and its at the shop today. I should hear something this afternoon.


Yea, I replaced all the gaskets from the heads up. Didn't replace 02 sensors though.

I tinkered on my POS over the weekend. My ignition coil was bad, and I had a faulty spark plug wire. This cleared most of the codes. This morning its still throwing a P0301 and a P0440.

I finally got the POS running well. But every time I post in this thread...something messes up. LMAO. I had bad plugs, and another bad set of wires. Replaced those, and its been running great for a couple weeks now.

I also did a Bravada axle/tube swap. The 4wd quit working when I replaced the head gasket. The swap fixed it...now i'm having a minor issue with the indicator lights.

Also, i'm not sure if I mentioned, I tweaked the torsion bars and swapped some 2wd s-10 wheels on it with some 31x10.5's.

I have a 3" body lift off of my 94 jimmy. Will I have any issues running it on the newer blazer? I know a 3" kit isn't made for the new body style blazers. I just want to make sure I won't run into any issues.

I managed to get my issue with the indicator lights worked out today.

well, this thread has come to an end. Over the weekend I was made an offer I couldn't refuse. A friend offered me a 1990 suburban for the Blazer. I've been wanting this body style suburban for a long time. I immediately started sanding/bodywork getting it ready for paint.
