Since the weather cooled my 29 Cadillac is running poorly. The engine ran great all summer when it reached an engine temp 170 -185F. Now the engine only reaches a temp of 140 - 155F and the engine has been flooding, car backfiring and all around running terribly. The car has an electric fuel pump with fuel regulator placed many years ago, regulator set at lowest setting. I placed another inline fuel regulator thinking too much fuel was the problem because the car was puking it all over the road but I still have the problem even though I've limited the fuel significantly from the pump. Maybe it's the fuel? Or perhaps its because the thermostatic controller isn't working to heat the engine up? Any ideas appreciated.
