Good morning,
I mention a problem I'm having with my Turbo X and it's driving me crazy.
After rolling a time with it, when you reach a traffic light and leave it idling, after a few seconds the engine failure light starts flashing and the engine fails. If I keep the engine at high speed, the error "cylinder 4 on failure" is stored.
I've also skipped the failure once, tightening down the highway to almost the limit of revolutions.
The coil 4 is new, the spark plugs are all new originals.
What can be?
Thank you

What code are you getting ? PXXXX, what are the X?

Get a compression check done. No other codes like P0018?

Sorry to absent me, I had family problems. The problem has gotten worse, yesterday when I used it, it ran out of power, it vibrated a lot and it's almost impossible for me to get home. Now I have failures in all the cylinders. These are the DTCs, the car has just 110,000km. Any ideas?
P0306 00
P0305 00
P0304 00
P0303 00
P0302 00
P0301 00
P0300 00

These codes provide no clue .. if there is no other codes u will need knowledge to diagnose it

There are no more fault codes. I missed the fault when I was pushing the engine above 4,000 rpm

Any component? MAF? O2 sensor?

Do u have a scanner that can read live data??

Lets start by checking short term fuel trim and long term fuel trim while the car is running poorly.
Is it running bad on idle only, or under load only or both ?
