Default POSSIBLE COMPUTER PROBLEM

RECENTLY HAD A 1800 T0 2200 STAHL TORQUE CONVERTER INSTALLED, CAR WILL NOT HOLD IDLE FOR FIRST TWENTY MINUTES, AFTERWARDS NO PROBLEM, BUT THIS HAPPENS EVERYTIME THE CAR IS RESTARTED, I DO KNOW THEY DISCONECTED THE BATTERY, BUT SHOULDNT THE COMPUTER ADJUST AND RESET AFTER 20 TO 30 MINUTES OF DRIVING. ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED

I DONT BELIEVE ITS THE STAHL CONVERTER CAUSING THE ISSUE, WHEN THEY DISCONNECTED THE BATTERY THE COMPUTER WILL READJUST TO ANY CHANGES WHEN RECONNECTED AND STARTED IN ABOUT TWENTY MINUTES OF DRIVE TIME, AS SO IVE BEEN TOLD, BUT THE COMPUTER IS NOT SINKING ITSELF GOES THRU READJUSTMENT EVERYTIME THE VEHICLE IS STARTED

THANKS FOR INFO WILL CHECK FOR LOOSE OR CUT WIRES, THE IDLE FLUCTUATES BETWEEN 200 TO 900 WHEN IT BOUNCES BACK DOWN THE CAR STAHLS, IT WILL KEEP BOUNCING AND STAHLING UNLESS I RIDE THE BRAKE AND GAS PEDAL TO KEEP RUNNING.

the computer will not re-adjust itself in 20-30 minutes..it could take days, or even weeks.. depending on how long it had been adjusting itself previously.

and for the love of god man... STOP THE FRIGGIN CAPS!
