Thanks guys, highly appreciate your suggestions.
I will check the spark plugs' oem specs and see if the installed ones are of correct specs.
One point, the plugs condition I posted was before I did the service. It had weak spark issue and spark was leaking to body. I was able to see the spark. There was hesitation when accelerating, and I felt missing like behavior when in 3rd /4th gear with rmp greater than 3.5k
With service, I removed springs from coils and gave them same acid wash treatment. Also the coils side, there was lot of rust in coil side. After service its a bit shinny and I did a test run of car, the acceleration is pretty decent, there's feel of power as compared to previous running. Also turbo sound is now quite noticeable.
I have found and serviced following:
- Air filter
- Intake air pressure sensor
- Throttle position sensor
- Spark plugs
- Ignition coils
Currently I am trying to find oxygen sensor and any other sensors which can be serviced at home.
I am trying to find service manual and so far unable to find it. I found for Pajero IO but for Mini no luck
And Eid Mubarak to you guys too
