When I started the vehicle up, it woke up really aggressive, there was a strong gas smell and it stuttered badly when driving her, along with the check engine light flashing at me when I did the test drive.\n\nAfter taking out the coil pack, I found that there was a lot of crap inside the springs within the boots...looked like dielectric grease gummed up by the previous owner. After cleaning all those springs and making sure they were straight, I took the new Spark plugs out (Champion Copper) I rechecked the gap and they were all good, after putting everything back together the old girl started up quick as hell, no shaking or anything. I drove it for 15 minutes and I had no issues whatsoever.

Pros: started up quick as hell, no shaking
Cons: strong gas smell, stuttered badly

Post inspection they mentioned that the spark plugs have gone faulty and was firing properly. They installed the new spark plugs.\n\nThe issue here is, I have driven cars for 10-15k without changing spark plugs and this is a new car from showroom which had bad spark plugs, also looks rusted, which was unexpected.

Cons: spark plugs rusted, faulty
Mileage: 4500 km
