Hi all,

 

My first post here so I hope I can explain my issue in good way

 

A month ago I did service for my skoda fabia mk2 1.2 tsi. The service place told me its time to change spark plugs as well at 180k km. Luckily I had bought spark plugs from autodoc so I told them I will bring my own.

Before changing spark plugs I had misfire issues when really pulling. Usually 1-2 misfires but everything else was fine. After service that problem is gone.

I bought bosh spark plugs with 0.9 mm electrode gap.

After 1 day of service I felt that the car was vibrating when idling. Now its not uneven idle of sort, but its like wave of vibration that goes through the car. If I stand outside or open bonet to hear, all looks fine. This only happens when engine is hot. When its cold, all look ok.

The biggest difference I see is when I am at very low rev and dont balance the clutch with power ie power is a little low or when car is standing and i turn steering. Its like engine stutter alot and then gets better. If i keep moving steering left and right, its stutter every now and then but there is no clear pattern. Its like normal idle, then stutter a sec, then normal.

Also I dont feel car has same power at low revs when I dont balance power with clutch. It dont stop but stutter alot. However I dont see issue at higher speed. Its runs like it did before.

Now I am not able to get hold of original spark plus specifications so if someone know where to get it then maybe I try to change spark plugs again. Stoll I dont know ifits spark plug related.

The garage did some visual inspection from outside and looked for codes but nothing . No engine light as well. I dont find much difference in fuel consumption after service however. Was expecting it to be a little better.

 

 

There's only one right type of spark plugs for this engine

 

Did you clean the throttle body (MAF?), changed air filter?

 

Did you only service the engine?

 

Have you checked the battery is in a good state of charge and health and all battery (and earths) connections are clean and secure?

 

Could be more than one issue with 180k km, how does your clutch and gear changing feel when driving?

 

Have you got any sort of scan tool?

These seems to be by NGK. Checking around here in forums, people dont seem to like them. But there was also an option from Bosch which seems like OEM for Skoda for sparks?

It was just oil and oil filter change and spark plug change. Nothing else.

Air filter seems clean but not changed, I have however ordered a new one just to change it as well.

 

Dont know about MAF or what it is, will check around.

 

Battery was change some 4-5 months ago, so its very new.

 

I think the gear changes have been a little jerky lately. The clutch has always engaged at a certain point mostly, so it doesnt have a long range when I start depressing it but it felt like a little down on power or maybe I am a little paranoid with this new problem I have.

 

I have scan tool, but the workshop guy said he ran the scan and could not find any issue. There is no warning light on dash board.

 

The only other thing I can think of are the coils but checking online I dont see any symptom's related to that.
