Hey everyone,

So, lately, my car has been bogging down. About 1200 miles ago, I had the same problem, so I replaced the spark plugs with brand new ones and it was fixed... But now, im having the same issue... But, a little different than before. The car bogs down when setting off and when driving above 3500 rpms. Not sure if i need to get my car retuned or what, but its annoying that the issue rises again. Any help would be awesome, thanks!

Heres a little video: (the car bogs down before the semi passes and after) (Skip to 2:39)

 

That's easy.

That's why you don't just go out and fit new plugs.
They only go faulty when there's either an engine mechanical problem or a tuning problem.


What you should ALWAYS do is take a good look at them to see what's wrong.

Photos of plugs?

 

My old plugs seemed fine and there wasn't anything wrong with them, so I don't think these new ones would cause problems... Thats why I'm thinking that it might be the tune on my car.. But I'm still unsure
