85 Cadi. Fleetwood, Brougham. Got it for free and have had problems with it. To date I have replaced fuel pump, filter, plugs, map sensor, air tube to cat converter, and misc vacuum hoses. When key is turned to on position the gas pedal will pump. If I do not start it quickly the sevice now light apears and the car seems to run rough. When I start it before the service now light apears seems to run better, however service soon light apears. The vehicle is also experiencing lack of power when driving. The engine sounds like it is lugging as if I am towing 10,000 lbs. When in park engine seems to run and accererlate fine.
Thanks for any help.

It sounds like you have a bad Throttle position sensor causing the idle module to pulsate. An older caddy problem.
