If the clutch is faulty you will have a poor pick up as the clutch might slip or make a shuddering noise while it engages all the time.
The fault seems related to idling settings on the fuel pump, check the throttle sensor check for fuel lines, fuel filter and fuel pressure- needs a calibration.
If the motor gets hot and cuts off and will not start for a period of time the problem would be the crank sensor. The sudden cut off and starting right back up can be due to dirty battery cable connections. Remove them from battery and clean all three of them with a wire brush and replace both bolts.
The fan is only supposed to come on when there is excess heat .. in normal driving conditions it doesn't start. When you start your car in the morning the fan won't come on because the engine is cold.
With a hot engine - and it depends how hot the engine is - the fan will only kick in to prevent overheating. In heavy slow moving traffic or a traffic jam, the fan will kick in if needed.
The air flow through the radiator is usually sufficient -in normal driving conditions - to cool the engine.
When you park up and the car has a hot engine, the fan will kick in. This is perfectly normal. It is caused by a surge of hot coolant triggering the fan sensor. Perfectly normal.
The fan then should cut out after a while .. maybe 2-3 minutes at the most. If the fan runs continuously that suggests a fault in the temperature sensor switch.
Next time - wait by the car and see how long it takes for the fan to quit after you have parked up. It should stop of its own accord after a couple of minutes.
If the fan cuts off after a short while, and your battery is becoming drained, that's probably a battery or alternator fault.
Remember: when you start the car the fan won't kick in at idle speed because the engine is COLD, and there is no reason for the fan to start up ..
The fan WILL kick in for a couple of minutes after you have parked the vehicle and the engine is hot
CHECK FUEL PUMP FUSE AND RELAY.IF BOTH GOOD LISTEN FOR FUEL PUMP RUNNING IN GAS TANK WHEN YOU TURN ON THE IGNITION SWITCH.YOU HEAR NO SOUND.SCAN VAN FIRST FOR PCM FAULTS SINCE IT CONTROLS FUEL PUMP IF PCM GOOD.FUEL PUMP IS BAD.IF FUEL PUMP RUNNING REPLACE FUEL FILTER.
It is hard to say without being there to fully inspect it and reading codes, but usually idle tracking is the fault. A code reader from either Wal Mart or most auto part stores will be perfect for you and though they cost a little they will save you so much money over the years. Most auto shops charge at least $30 just to hook up a code reader and diagnose your vehicle. Make sure you get the one that is universal and for many makes. That way no matter what cars you buy, you can diagnose them yourself
The 3 series suffer badly from camshaft sensors and on your vehicle crankshaft too. Replace all three sensors and your problems are gone. You will notice that the old sensors have a step in them while the new modified ones dont, good luck
