The cables are probably broken on the regulator assembly. You'll probably have to replace the unit.

The parking brake mechanism may not have released due to a frayed cable. Have it towed to a qualified technician so you won't cause damage to your rear rotors.

sounds silly but did you try using the dimmer switch, either the light or on the dash usually on the left. litlle wheel that dims the dash and radio lights.

sometimes the shift sensors can go bad on these vehicles and would cause hard shifting in certain gears and would have to be replaced, a lot of times, going to a shop and have them run some tests on it would confirm more than likely a sensor. also, check your fluid... if it has never been changed, then it may be time for a fluid and filter change for the transmission, that makes a huge deal in it most times, also run a bottle of lucas transmission in there as well and it will help with any hard shifting and any slipping if it is not the sensor. hope this helps

You can't rule anything out yet. It could be a plug or injector among other things, but probably not low fuel pressure. If you have a code 300 and nothing else, you may have to wait until the problem gets bad enough to set additional codes. And if any of the sensors fail, such as the cam or crank sensors, you'll get a code for those to be tested. Have the plugs been checked or replaced in the past 30,000 miles ?
