Hi guys

I hope this thread will help me.
My problem is when I start my car, it sound like a subaru
I remove all sparks, spark 2,3 and 4 is in normal color and the spark 1 is Black.
I decide to change the wire spark plug and the two ignition coil, But the problem is still here.
Than I made a compression Test on each cylinder and the resut is 11 bar +/-0.2 for all
after the test I decide to change all injector But The car still run on 3 cylinder.
I have an EGT sensor on the manifold ( the hole is on the cylinder 1)
and when I start the cear the EGT gauge stay on the 0.

So now I need some help so I you have any idea let me now

 

any idea ??????????????

 

well if u pinpointed it to the #1 cylinder not firing did u try changing the #1 spark plug?

 

I would use a spark checker to be sure the plug is firing. After pulling number 1 spark plug out does it smell like gas? Is it wet?

 

Yes I change all sparks and yes all plug are firing

 

if its black your injector may be stuck open.. is there gas in the oil.

 

any tears in the boot? your boot may grounding out along the spark plug housing.

 

ok

there is not gas in oil and the boot look good !!

 

Bump

 

BUMP, bump

 

vacuum lines, fuel filter, injectors.....

 

stuck open injector.

 

stuck open injector. start the car and feel if the injector is clicking. or get a noid tester.

 

Stuck open injector??
But mine injector are news RC 750CC

Is it possible the problem come from the ECU ???

 

Triple check vaccum lines, all are fit proprely
but do not do a leak test yet
