Hi Scotty, I have a problem when driving at low speed in particular heavy traffic where I'm stopping and starting, the car seems to miss or even shudder when lightly accelerating. the car has only done 78000 kms. I have fixed a vcmuzzler 2 to eliminate eco mode but still doing it. I have checked the spark plugs (NGK iridium) and one appears to be worn more than the other 5. There is no engine check light on and still has power. Love your channel and any suggestions would be greatly appreciated.

Well if one plug is worn more than the others., I would do a wet and dry compression test of the engine first to see if that one cylinder has a problem internally. If it's not that unfortunately there are scores of different things that can cause hesitation like that from weak fuel injectors to even transmission problems
