Question about 2000 Jaguar S-Type
Engine light came on 1-2 month(s) ago for 1 day and then turned off. Yesterday it started stalling on and off even more so when more gas is increased. This am the engine light turned on for a while and then it turned off. Been fueling it with regular gas due to high gas prices along with octane or gas cleaner every other fill. Could it be the air or fuel filter, fuel meter, mass air flow or throttle plate?
If u havent had it serviced for a while then its likely that a filter is cloged, time for a service.

yoy need to change both the Air Mass Sensor and throttle valve actuator to eliminate this problem. The actuator is pretty pricey but thats the ONLY solution i'm afaraid.

it possibly clogged the o2 sensors when it cleaned the gunk out and the maf might even be on the air box or bolt on the intake directly or it can be in the tube but probbably need to check and see what the codes are with a scanner

Look for an IAC sensor (motor) Idle Air Control.
Usually located on side & front of throttle body. Not 100% sure which type you'll have but if you have pintle type (pointed end) Remove it, spray it well with throttle body cleaner as well as port it came from, and retry. If it cures it temporarily & starts to do it again, replace it.

following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exceptions to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.
