Possible transmission issue. Does it feel like it is taking off in first?

 

If i barely touch the pedal i can slowly build up speed and feel each gear engage smoothly. Now if i take off with even a 1/4 of the pedal down i feel like im driving into a 200 mph head wind. Its definately getting worse but something i must note is initially it would take off, build up rpms, shift and bog down tremendously.

 

Thought I'd take out the upper o2 sensor and drive around the block before taking it to the shop . Man what a difference that made. Guess I'll order me up a cat now

 

Not to confuse things, but if you have to order a cat, try to source an OEM one. Some of the after market ones have been known to cause erroneous check engine lights....

OR, you could upgrade to a 2.5" ZZP Downpipe with highflow cat (again, it runs the risk of an erroneous check engine light).
