Fuel traces in EGR Valve.

[Amf3ar]

THanks alot for the quick reply!

Is engine compression reading good 150PSI x 4... (10.4 Bar or ,1040 KPa.)?
- seems so. I'll make another test but the last one (3months ago) were in specs.

Is spark timing correct?
- still have to check this.

is the injector cleaned ? (remove and cleaned with ultrasonic cleaner? , if fuel was bad or rust this injector will fouled up)?
- I already checked the injector for leaking...no fuel until engine starts, no dripping after it stops.
Previously I replaced the fuel tank (cause of rust) with a brand new one, same for fuel filter and fuel pump.
After that I cleaned the TB and injector with TB cleaner and used a bottle of injector cleaner (additive) in fuel tank.
What I need to do now is take the injector to someone who cleans it with ultrasonic cleaner...but, looking how it sprays seems ok.

Is fuel pressure at SPEC?
- still need the pressure gauge to test it (i'll buy it asap) but this is the fuel pump currently installed: https://www.autopartspro.co.uk/ashika-7998817
I replaced the bad FPR with a working one (no fuel leaks from vacuum hose)

Does the ECu flash code 12 (good) on demand? 'Diagnostic jumper clip/wire"
- Yes

Does misfire get better or end with 02 (lambda) sensor is unplugged,? oxygen sensor)
- Must check this

When the TB was removed was the TV throttle valve closed 99.9% (.0005 gap. 0.125 Millimeters, aprox. so close water fails to pass? the gap)
- Yes

Another thing is the exhaust smell...seems like smelling of fuel...just checked all 4 sparks and they are clear and dry,,,
Just another question: how must I set the air bleed crew? I really dunno if the previous owner moved it or not :/
