Odd Shifting and bogging down?

[JBlacks]

Well something pretty weird is happening to my camry. I had a terrible exhaust, full of holes and the muffler wasnt even attached, the y pipe needs to be replaced also.

I did a complete cat back exhaust fully welded w no leaks still have to do the y pipe.

Now before i ever touched the exhaust i noticed it started bogging down no matter the acceleration. The car will shift out of first at around 4k, and then sit at 2900 rpm for quite a few seconds before gaining any rpm. Could plugs and wires be the cause of this? No CEL is on. Also i notice this more when it is hot and the ac is on at all, but it happens with the air off sometimes when its cooler as well.

Any ideas?

your hole in the exhaust is causing false readings, fix it.

So the Y pipe is still torn open? Like chronti said, it'll hurt it. Specifically the low end torque. Even at that, under light throttle it should shift at 18 (2nd) and 25-28mph (3rd).

You have to rev it to make it shift? What's the fluid look like in the trans, smell like?
