a couple of things here. If your parking lights dim then brighten, then you really need to clean your battery. That also may be why your having trouble while driving. Charge the battery up and have it checked, most auto parts stores do this for free. Then get some choke cleaner and clean your throttle body especially around the IAC and TPS. Make sure you have a clean air and fuel filter as well. If you still have the problem, then have a pro check your TBI unit for a good connection as they tend to breakk/disconnect....
