It is true that code 34 can be a speed control code, but also an EGR valve code. A malfunction there would cause a change in idle. You might need to replace that, or make sure the wiring is working correctly

I think i work better at night,just got back in from poking around at the jeep.What i thought was the EGR is actually the TPS. So where the hell is the EGR

It is under the intake directly under the throttle body

I'm almost wondering if the speed sensor might have something to do with it
