Default My car is stallling out a little

My car is stallling out a little I guess you could call it stuttering. Wide open throttle it runs pretty good but like when I first start it up the RPM's go up and down up and down and up and then it will idle out. the I take off in first at low rpm and it stuters or wants to stall but doesnt turn off. Same in high gears but low rpms it stutters or wants to stall. I had some issues with my headers and took off the headers put a new gasket in and a new Y pipe and no longer have cats now. Seems to have started since this. I have no O2 sims. I unplugged the battery and removed the pcm fuse/pcm bat and let it sit for the night if this persists tomorrow could it be because it is running rich or maybe an 02 sensor help I am lost. I thought it my be my electric cut out pipe so I disconnected it just to make sure it wasnt grounding out or doing anything else same issue though.

Any help is very much appreciated.

What modification did you make right before this started happening?

Has it been tuned for the larger TB yet?

The Y pipe but that doesnt make sense it ran fine for like 2 days then I raced a new civic si and demolished him right after that it started.

Check your headers for exhaust leaks around the heads.
You didn't happen to spray water on your O2's did you?

Heads up for some people. The problem is resolved and a new proble has come up. LOL Last night I was driving to the Houston motorsports 1/8 mile track and was just going to watch but my car had been stalling out right so I opened the cut out just to make some noise. It is an electric one right then I decide to close it as I am getting closer to my friends house and I hear a popping noise coming from underneath the car on the passenger side. This is where the cut out is located so I stop and look under the car and the little motor thing is popping and it is bright red. It Had already melted the rubber off and then your not going to beleive this. I went to go to the battery to unhook the cable for the cut out and I hear a loud pop under the car and see smoke coming out. I go back and look and the only thing there is the wires hanging and the cut out closed but the motor was gone. I dont know what the hell happened. The good thing is the stutter is gone it must have been the cut out pipe was shorting out. I had already unhooked it once but didnt seem to fix the problem but I guess I didnt disconnect it long enough. I even raced my car last night it ran great. The bad thing is I need to go and buy a new electric cut out anyways I figured I would share this just in case somethig similar ever happens to you guys. After that I just cut the cables and it has stayed closed. Crazy stuff I would have never imagined this.

Up your idle raf to the highest you can stand before it pulls you along.
Increase idle timing in both table.
Increase rpm at idle to as high as you can stand.
Make sure idle afrs are a little rich of you can. Down near 14.0 is better than up near 15.0
