Good afternoon everyone, I want to share my case and see what solutions we might have, I appreciate in advance your reading and contribution to this thread, thank you very much.
I have a 2020 Honda Civic X 1.5 turbo and at 106,000 km it started having problems with the injectors and unstable idle. It has always been maintained on time and used 98 octane gasoline.
Currently, the following has been done to try to solve the problem:
Fuel pump replacement (under campaign)
Replacement of injector rail and seals
Injector replacement
Throttle body cleaning and seal replacement
Replacement of PCV hose (it was cracked)
Air filter sensor cleaning
Learning
For now, the issue with the jerking due to the injectors is resolved. The problem is that the idle remains unstable and Honda hasn’t found the solution (the car has been in the shop since 02/19).
I appreciate any input to find the solution and get my Civic back on the road.
The spark plugs are new, but after a few kilometers, the injectors started to fail… one of the injectors was leaking and another was dripping, honestly, I didn’t notice any change in consumption or power. It could be that the new spark plugs were damaged because of the injectors… let’s see what they say at Honda, but honestly, the fact that they can’t find the fault makes me confirm that they are useless and just parts changers… they cleaned the MAF sensor, but I doubt they checked anything else.
I meant the injectors if they were dirty, but yes, they were defective. If there’s oil on the spark plug threads, have them change the PCV valve or at least clean it (it’s replaced every 80k kms I think), it costs about €44 and you can change it yourself if not.
I went to the dealership in AlmerĂa and they only knew how to tell me the name of the fault, and they already wanted to start changing everything for me, well, they have no idea here either…
Have them check the air filter and the electrical connection of the MAF sensor, just to rule it out…
etc.
I have already paid the €1,400 for the repair of the injectors, the gaskets, cleaning of the throttle body and its gasket… now they tell me that everything they have to do is at their expense.
What do I do, do I show up again (I have already gone several times and filed complaints for various reasons until they gave me a replacement Hyundai i10) and tell them how to do their job?
Honestly, I don’t know how to act in the best way in this case since I’m quite tired of not having my car that I keep paying for and “use” to go to work…
I know you’re tired of the subject, but while looking for the reason for my failure, another clue for yours came up in case it helps you:
• replace the oxygen sensors.
I’ve never done it, to be honest, do you recommend doing it even if I don’t have any errors? I suppose any spray cleaner that is isopropyl alcohol would work, or does it have to be specific like the one you mentioned?
I wouldn’t risk using another product since those sensors have a kind of film that could get damaged, and it’s quite an expensive sensor. For €10, I wouldn’t risk something worth €80 (just to name a price).
It’s just a simple resistor; basically, if you aren’t going to use that specific product, just make sure the spray pressure isn’t too high so you don’t break the thin wire. You can use brake cleaner and isopropyl alcohol, but since you’re at it, you might as well use that—for €10, it makes your life easier and minimizes risks. That said, if you use the stock filter and it’s been changed on time, it’s probably not even necessary, but for €10 and 5 minutes…
