My toyota corolla 2003 starts and dies whenever I starts it in the morning. It stops dat only when the engine guage at the dash board reaches half mark. It takes me about 10min to reach that temperature by continuing to hold the throttle ( to riv d engine) be for I can drive. But immedately d engine gets hot all these problems disapears. I hv changed the ideal air control valve, and set the engine but it contiues. Pls what could b the problem

Firstly go for a scan. Is your thermostat still I'm place? because it takes long to get to the running temperature.

^^^ His car might have a vacuum leak. In this scenario no scan code would be triggered.

Yeah, he should check for the thermostat and make sure the temp sensor/switch is well connected..

d thermostate is there, i did a scan it shows P0300, 0301, 0302, 0303, 0304, P0016, and P0100

Your car has three major faults.

1. P0300, 0301, 0302, 0303, 0304
This is a case of random / multiple cylinder misfire. You will need to replace the spark plugs (4 in number) and perhaps service the injector nozzles. if this codes still persist, then you may need to replace the ignition coils but I pray you will not have to get to this point.

2. P0016 - Crankshaft Position / Camshaft Position bank 1 Sensor A -correlation
Probable cause - Wiring, Crankshaft position sensor, Camshaft Position Sensor or mechanical fault.

3. P0100 - Mass Airflow Sensor / Volume Airflow Sensor - Circuit Malfunction
Probable Cause - MAF/VAF Sensor.

Once you fix all these, your car should be running fine again. Best of luck with your repairs

thank u, i will work on it
Hello Johnson it is P0010 not P0100, thank u

P0010 - Camshaft Position(CMP) Actuator / Intake/left/front bank 1 - Circuit Malfunction

Probable Cause: Wiring, CMP Actuator, ECM.

All the best but be sure of the code whether P0100 or P0010.
