Need some help
For a little while now my car has been stumbling when in low RPM's. if I upshift, to 5th going 40ish and floor it you can feel the car shake for a few seconds, and then it seems to "pass" imagine like you're taking a huge dump or something.
I've tried fuel injector cleaner in the gas tank (not sure how well that works) but I'm not really sure if that works that great. Only code i'm throwing is my front o2's being lazy from the LT's.
Any ideas?

How new are your plugs? What is your gas mileage like?

i was gonna say opti, but u dont have one of those. best way to test that thing is to stick it in 6th at 50, and hold on to something if its bad.

plugs I honestly don't know... they aren't something I have a fond memory of after my headers Mileage is 18ish city, 26ish pure highway. Could the o2's be confusing the motor? I checked the wires and none of them are burned. One is reeeeaaal close to a header pipe though.

Well I don't think having cats could be an issue. The rear o2's have nothing to do with engine mangagment, and the front o2's aren't affected by cats or the lack thereof.
But I have o2 sims for the hell of it. I might do a full tune up just for the hell of it. How long should that take me? The car was two times worse today, I felt like I was on a bronco.
It also seems like it's worse when the car is cold. Once it warms up it seems to get better. Is this a trait of a certain problem.
