C320 ignition problem
Hi
I'm new to this forum. English language skills are not very good, but I hope that you will understand what I mean.
I have C320 and problem are next:
RMP speed to be high (over 5500 rmp / min) should be the next fault, cylinder 4 ignition failure. Fault will only cylinder 4
The fault is cleared when the car stops and starts again.
Attempts have been made to find fault as follows:
Experimented with two different MAF sensor to no avail.
Also tested a faulty MAF sensor, the fault code came MAF sensor.
This I wanted to test that other fault codes comes through
Spark plugs replaced.
Replaced ignition coil cylinder 1 from cylinder 4 Changed the plug wires to each other.
Secondary air injection shutoff valve cleaned and replaced with each other.
Changed the fuel nozzle cylinder 5 from cylinder 4.
changed the air and fuel filter.
I do not think that the problem would Camshaft Hall sensor, crankshaft hall sensor or Knock sensor,
because the fault is cylinder 4 It would be quite a coincidence that it hit the ground at the same cylinder.
Is the only chance that the ECU would be broken?

Unlikely to be the ECU but not impossible.
Replace the coilpack on No 4 with a new one.
Fit new plug leads.
Check engine harness wiring to No 4 coilpack. Corrosion etc in connectors.
Check fuel pressure at the Schrader valve on the front fuel rail. It should be > 3.8 bar or 55 psi while cranking.
Good luck.

I have to remove the ECU wiring connector and watch if there's corrosion.
Replace the coilpack on No 4 with a new one.
I try cylinder 1 coilpack and plug leads.
error is as follows: The cylinder 4 is dropped completely out of the ignition system.
Fit new plug leads.
tested in the cylinder 1 plug leads.
Check engine harness wiring to No 4 coilpack. Corrosion etc in connectors.
Coilpack connector ok. no corrosion
Check fuel pressure at the Schrader valve on the front fuel rail. It should be > 3.8 bar or 55 psi while cranking.
fuel pressure without checking, but I doubt it.
Need to measure it.
Thank you for your suggestions
Just came to mind have to change the spark plugs still cylinder 1 to cylinder 4 and experiment with possible transfer of the fault when cylinder 1
I remember the failure occurred after I had renewed the spark plugs. I do not believe in it, but there is a small chance that the spark plug had broken
I hope so
