Engine Performance problem
1992 Cadillac Brougham V8 Two Wheel Drive Automatic 127000 miles
92brougham 5.0L throttlebody: excellent mechanical condition, easy to crank over yet takes a long time to start, then very unstable idle and wants to nose over (die) at slight throttle. Drives fine on highway with less power up hills. No pinginging or black exhaust, no backfireing, no overheating. I have never replaced fuelpump or any fuel filters. Ignition wires, plugs, spark is very good. This happened suddenly after driving fine and then restarting a few hours later.
