check the Relay near battery one which is connected up to a diode in the loom (3 relays located here, its the one closest to the overflow reservoir) i have had and still have problems with this relay for quite some time now. Probably just an earth problem.
check for corrosion on terminals/spade connectors and under the plug not just the relay.
this relay controls the injectors

exactly what u r stating is caused by CAS or AFM malfunctioning
pull the codes from the ECU


Code 11 - Crank Angle Sensor circuit
Code 12 - Air flow Meter circuit
Code 13 - Coolant Temp Sensor circuit
Code 14 - Vehicle Speed Sensor circuit
Code 21 - Ignition Signal circuit
Code 23 - Trottle Switch circuit
Code 24 - Neutral Start Switch circuit
Code 31 - System Pass (OK) (Non A/C), A/C circuit (A/C models)
Code 32 - Starter Signal circuit
Code 34 - Knock Sensor cicuit (Turbo)
Code 44 - System Pass (OK) (A/C models)

ok
Behind your passenger side kickpanel is the ECU (Engine Control Unit)
there is a screw on the side Diognosic Mode Turn this fully clockwise carefully and turn your ignition on
in the peep hole there is 2 LED's Red and Green
RED = Tens
Green = Units
So if red flashes 2 times then green 3 times that means code 23 Representing Throttle Switch
press the throttle to cancel this code
Other codes to cancel is 14 Speed sensor(u can leave it) car needs to go over 10kms to cancel code
24 Neutral Switch.. Move the gear shifter to Drive then to Neutral and then park to cancel code

Then keep an eye on further fault codes coming up
Write down the numbers for us to help u with
codes are seperated with a slight pause
Goodluck buddy
