Fuel injection Relay! These things fail more when it is warm out (during the summer etc). It is a large relay located under the hood inside the fuse box. It is about the size of 2 relays put together. It is either red or green. When it gets hot out, the relay swells up an separates and causes the car to stall out intermittently.
the filter has to be really blocked to prevent fuel flow and even then the cart will idle
I suspect the your fuel pump is a problem either from a faulty fuel pressure regulator or relay for the fuel pump
I am not saying that it is not the fuel pump , just to check the other things first

Purge solenoid is located on the radiator fan housing on the driver side. Has a vacuum line from the throttle assemble to the solenoid, a 2 wire connector and a line that goes down and to the pass side of the vehicle.
It is located just to the rear of the turbo on the exhaust pipe. It is the first component after the turbo. Should have an 02 sensor just in front of it.
the malfunction lamp is on to tell you that there is a fault in the system of the engine and/or gear box. It requires you to have the fault codes read and to have the fault fixed. It is there to notify you that something has gone wrong and to have it fixed before it becomes expensive.
