1996 3.8L Miss

I'm going through the same thing myself. Same year Camaro, a few more miles (132k. started missing at 125k though) I've done alot of things with mine and I'm not quite sure what else. All I can say is check everything you can think of and a few things you don't think of. basically check everything. I'm about to give up and just drop a low mileage engine in there for the time being and since it won't be my DD for much longer (maybe 7 or 8 months tops) it should last longer. But check everything and listen to what some of the other guys on here say. They definitely know what they're talking about.

I do have an Ses light but it's from an air mod that has been on since 90k. It's not throwing any codes, and as far as cylinder goes, it feels like the whole engine is about 2 die. It has a nasty violent shake when it misses.

The problem is still there, I took the "air chip" out, which I can't feel any difference, and I had a mechanic run a diagnostic test on it. It kick of an O2 sensor, and a Crank Position Sensor. I have since reset the SES light to see which one trips it first. I have never heard of Crank Position Sensor, so would that cause it to miss?

Do you know specifically what the 02 sensor code was? Depending on the code, it can give you some valuble information in regards to how the engine is running and if there is a specic problem on a certain bank or what not. Long story short, if there is an engine issue elsewhere, that can be leading to your misfiring problem. If you could give us the specific code, we could help you out a little more.

It was the left bank O2 sensor that is all the mechanic told me. I have cleaned all the connections on all sensors with the cleaner stuff available at Autozone, and reconnected them. Maybe this will work, because my waterpump went out a few weeks ago and slung antifreeze everywhere.

Well I played it the easy way out with the O2 sensor, and replaced all four of them. I figured at 120,000 they were shot anyway. My mechanic is currently replacing the Crank Position Sensor, and he said that on the 3.8's this seems to be the only problem they have. I'll keep you guys updated if this fixes the problem or not.
