It seemed fine driving home yesterday and this morning. It wasn't until after I ran it all the way through 1st and 2nd that the idle started acting up. Basically it sounds like it is going to stall and the RPMs jump between 200-800.
The check engine light also came on, so I scanned it and got these two codes. P1133 and P1153 They seem to point to the front O2 sensors, which obviously don't exist anymore. Plus I don't see why the lack of O2 sensors would mess up the idle.
A few weeks ago I had solo high flow cats installed. Because of a stripped O2 sensor, I ended up driving the car for several days until I could get a replacement. That didn't cause any issues other than the check engine light staying on.
Just to avoid confusion, I replaced the solo cats with the kooks high flow cats. Just stating the above as an example of driving the car with a missing O2 sensor.
So what do you think could be causing the problem? Could it have anything to do with the spark plugs or is the PCM causing the problem because it doesn't see the front O2 sensors and they were not properly deleted during the tune?

TR55s
First Put the Stock Plugs Back in, They work best in your car.
You CAN NOT delete the front O2 sensor they are used for monitoring and fine Tuning of your engine.
1133 and 1153 come on for Front O2 sensor in activity, so I suspect your front O2s are in place but the Long tube headers and no cats are causing these codes, these codes must be turned off for LT headers, Your Tuner should know this.
You Can However Delete the Rear O2s since they only monitor cats and have no affect on the tuning, and all codes for Rear O2s, about 20, need to be turned off.
