OK so Im driving along and out of nowhere I go to step down on the gas and it just revs. Once I hitt about 3 thousand revs it shifts hard, and to get it to move it downshifts and pretty much floors it. Only other thing is that im running 2 o2 sensors for another couple days and its running much much much too rich what do you think the problem is?

 

which 2 o2 sensors? You only need the fronts. The rears have no affect on fueling.

 

I dont have the ones in the cats and since then my cars been running like ****.

 

The ones behind the cats? Did you install headers or something?

Removing the rear o2 sensors will throw a code (emissions) but will not affect fueling.

 

yea i did long tubes, no its def running rich i can smell pure gas coming out the back and the car vibrates rapidly and gets worse gas milage

 

headers shouldn't make the car run that poorly.
headers shouldn't cause the problem you've had with shifting.

I would first check that the wires for the front o2's are not melted. Check that you got all the plug wires on all the way. The car should get tuned for the headers, but you've got some other problems.
