It'* hard to tell, but I think your #6 sparkplug wire looks real close to your O2 sensor wire, those shoudl not be touching, or even close to each other. Interference from teh plug wire can throw off the readings from the O2 sensor. So let'* start with that issue. Another thing to check is your air filter. I had a Fiero years ago that sucked up a paper towel, and every time I put it down is lost power. Easy check, easy fix if it'* the problem. You shoudl be able to see sun light threw the filter, if not, replace it.

I feel really stupid, I dont even know where the O2 sensor is or what it looks like.

Here'* another picture.



Look at the dirty manifold at the top just right of center there'* something sticking out, kind of gold in color. That'* it. It'* on your rear manifold, or there abouts. Should be right where the manifold connects to the down pipe. The wire should plug in right around yoru fule lines. It should be the only wires coming up from the manifold. Keep those as far from the sparkplug wires as you can.

Im pretty sure I saw what you're talking about (went back out to look) but I dont see anything I can do to move the wire, Its plugged right into the spark plug which is almost at a direct angel to the sensor
