Okay this is what I got based on you request Start up: https://www.youtube.com/watch?v=0d3fdzEoHTE After restarting. https://www.youtube.com/watch?v=b4c26u-XtM4 So I'm back home now where the weather is above freezing and the funny thing is that the problem has persisted so far which is great becaus...

This is how it looks on the throttle app during start up vs after the restart

After the restart. https://youtu.be/KLCIle8Migg


Oh and btw I have changed the sensor without any difference

They look ok except for initial fuel trim. Can you repeat test and check both O2 readings and post They should be fluctuating so can you give max and min fings and whether OL or CL operation? Okay, now i have 2 days left before i leave to my hometown where the weather is better so tomorrow i can do...

The thing i don't get is why the fuel trim goes to zero when the car is having the problem. As well as why the fuel trim always is negative before the issue occurs but turns positive after the restart.

I'll take a look at the readings tomorrow and report back

Yes but you need to compare with ambient. You have told me what the ECU sees. Take the 3rd pic for example. If engine has been running for 20 mins and outside air temp (if car was outside) was 12 deg, then those readings are all over the place Ambient temp was 0-1 celsius and those pictures are tak...

Does the readings tell you anything about the possible cause?

Well when the mechanic switched the timing belt he said that it had been wrong by two teeth, but it's a well known shop so i'm confident in the fact that the job was done right this time.

I'll have to take a look at those plugs when i get the time for it.

The timing belt has been changed a year ago. But i've been thinking about the coil pack for a long time now. Is there anyway to test the pack? I do feel that the car don't have the 110hp that it's supposed to have.

I've recorded how the issue presents itself if that help.

Although weirdly enough i got another code this time which i've never gotten before which was the p1336.

Here are the results of the obd scanner. Does this help my case ?

No clue, bought the once recommended at the auto parts store, i can check them tomorrow. But shouldn't there be more issues if its the plugs rather than only when it's freezing cold?

The plugs are about 1 year old and the oil is the recommended 5w-30

Oh.. well okay i've learned something new today then
I'll order a new sensor and hope it solve the issue

So i removed the crankshaft sensor to see which one to order and i came across this. The crankshaft is missing some teeth, is this normal?

Okay thanks for the help and info, i'll have a look at it tomorrow to se if there are any signs of damage. Otherwise i'll just order a new one.
