After a 300 miles trip I parked the car in the driveway. The next day it would turn over but not start! I had a couple of mechanics look at it and got various suggestion as to what the problem was. Changed the fuel pumps, fuel pump relay, fuel distribution system, idle air pump. still the same results. If I crack the big throttle a little bit, the engine will start, however any depression of the accelerator and the engine will die. If I force feed it with the throttle linkage it will run at the higher rpm but will just die when I stop feeding the throttle. At this point I don't know where else to look!! HELP!!
