Hi Brian sorry not in TX but I am posting here because correcting TW is entertaining
Many ECU units are fitted with a '
limp home mode'.
NOT GIMP MODE When it detects that something semi-serious is wrong, it enters the
limp mode, which means that the engine won't rev beyond a pre-programmed speed. You can re set some computers by disconnecting the battery for 15 + minutes and it may make the vehicle drivable to a service area, however if it is a serious problem you may damage the vehicle. If the check engine light stays off after the battery disconnect it may have just been a plug misfire. If it was serious the then check engine light would come back on immediately. Autozones and Advanced Auto Parts will run a free scan to tell you exactly what your computer says is wrong with the vehicle.
