The engine stalls immediately on a cold start - or when I have attempted to start it several times, the idle starts hunting up and down until it slowly settles. Touching the gas pedal helps a bit as it warms up the engine quicker.
Things which are already done:
- Checked for codes - none found
- O2 sensors changed
- IMS changed
- Clutch changed
- Chain guides changed
- Camshaft deviation checked
- MAF changed
- Checked for vacuum leaks
- AOS changed
- Plugs + tubes changed
Once hot - car starts fine though performance doesn't seem optimal during driving.

I hope someone can help me out - getting quite tired of this. Please check the video for reference |
1. How many miles on the car.????
2.hookup a scanner to the OBDII and look at coolant temp when dead cold,
before you try to start it.
What does it read????
A faulty Temp. sensor can show a false (warm) coolant temp when the engine is dead cold. The ECU thinks the engine is warm so it does not enrich the fuel (pulse injectors longer) for cold start.
Let us know what you find.
