I have a 94 seville SLS. I had a non Cadillac mechanic recharge my AC. He disconnected the battery and who knows what else to get the AC system back on. The AC is working fine.
The fuel pump, filter and cam sensor have been replaced without solving the problem below.
The problem is:
After the A/C recharge, when the car is hot enough to have the radiator cooling fans start up the motor dies when you step on the gas.
The car runs fine until it heats up and it will idle forever without overheating but when the car is hot and the gas pedal is depressed the car stalls.
The car easily restarts when hot or cold and the car runs very well with good performance when cold or warm until it gets hot enough to start the radiator fans, about 10-15 minutes in this weather, then stalls.
How can this be fixed?
