Honda civic x turbo 2016, missing issue

[moeen.a.rana]

Guys, so new updates which is summary of last 30 days efforts.

Following things are done:
1. Throttle body service - No luck
2. Complete checkup of Air leakage - no issue found
3. Testing new plugs + air filter from another Civic x Turbo (which was working fine on that) - No luck
4. Removed Cat - Got little improvement in pickup but this was also not culprit
5. Intercooler replaced with another one for testing - no luck
6. Fuel injectors cleaning done & tried another one from Bilal ganj - no luck (Pressure was checked and it was 60)
7. Fuel filter changed - no luck
8. Finally tried Turbo from bilal ganj - no luck

So what should be next steps now?

What about the gear replacement?

[highroller]

Did you use your electronic wastegate controller or replacement?

[moeen.a.rana]

It was also replaced with new turbo tried

[moeen.a.rana]

This is not done as multiple mechanics said this is not a transmission issue. Also since that is expensive and much time taking so I not attempted.

[highroller]

Extremely weird behavior. Unfortunately I don't think much is left to do.

I was on the same boat a year before with my rebirth in the end i sold it and bought an X same missing issue and no mechanic left to which i didnt visited

[farooqk80]

are you sure it's not a placebo effect?

[moeen.a.rana]

Sad to know bro... I wish we can find better mechanics to identify. I'll keep everyone posted once I get any hope.

[moeen.a.rana]

Obviously not buddy. Anyone who drives can notice this.
Obvious missing, jerks while driving, low rpm on idle, no pickup like turbo or even civic 1.8 style.

[moeen.a.rana]

I'm again going to visit honda Fort and try my luck there. I thought EGR might be culprit and there are chances that the replaced turbo part was not working fine as well. Just a thought coz it's from bilal gunj.

[SpeedDemon]

Fuel pressure at 60 (psi i presume) is the one from the pump in the tank. This is a direct injection engine and there is a secondary mechanical fuel pump increasing the pressure in the fuel rail for the injectors to fire properly.

Please get that checked. A faulty pressure sensor could be a possible problem.

The pressures are much higher in the fuel rail for Direct injection engines.

Cheers.

[moeen.a.rana]

Yes it was also cleaned when fuel injector were cleaned.

[Spano]

dirty filter add to this problem. The diagnosis is not that simple as checking or cleaning the throttle body since it is further onwards from that in the intake.

Removing the intake manifold will reveal the condition of the intake valves and the manifold itself...

SInce all else seems to be fine, kindly do get this checked as well.

your story is very painful.
I can understand the tough time you are going

[Spano]

Please get compression testing
and share the readings.

since you have done most of the things
Valve seats or Valves related issue causes missing and random RPM drops.

this is the easiest thing you without harming your engine.
please do share the results in private message, if you have my number whatsapp. you can take it from Zubair @ Shehryar

[emzee92]

Honda Fort or Township!

[moeen.a.rana]

Sure I'll get that checked and share with you. I'll get number from zubair.

Sharing another update.

Update :
Finally car was given to honda Fort on this Monday morning. They spent 2 days so far and unable to identify the issue.
Few things:
1. Replace throttle body from another civic turbo
2. Replaced plugs and coils from other civic
3. Fuel injector cleaning
...........
I took my car back from them due to holidays but they requested to give them car again on Monday for couple of more days.

I'm not sure if they did engine compression test but I'll ask them to do that.
.........
I visited anther electrician names Zaheer electrician in Walton plaza. Those guys spent couple of hours and they suggested to get car computer replaced as that seems to be culprit. Secondly he mentioned that there is an issue with transmission too. But first thing should be computer check.

What you guys suggest ECU can go wrong by any means?

[moeen.a.rana]

Update:
I got my car back last night from Honda Fort & they were able to find main issue finally after further 4 days of investigation. My car is almost back to its original performance i had earlier.
The issue was with T MAP sensor as it was sending wrong reading to ECU and hence Turbo was not turning on.
During these day - they replaced Fuel pump, EGR, Air Filter + box & pipe, then Turbo, Checked AC, wiring etc... And finally they started replacing sensors 1 by 1 and came across this MAP sensor issue. Good thing that i must appreciate is they were actually replacing these from some Manager's car as i saw that car as well.
.....
I still feel little missing/jerk when using heavy foot that was actually the problem in start. Ill visit Honda Fort guys again tomorrow as they mentioned to do a test drive & tell them issues I feel.

@highroller @Spano - thanks guys... ill see you soon & show you car.
