Had a full service done last week and since then the car feels slightly off, not dramatically, but the throttle response seems lazier and it's idling a touch rougher. I'm wondering if I'm imagining it or if something wasn't done right. They said they changed the oil, filters and plugs, so it should feel better if anything. I'm near Musaffah Shabiya so I've been looking at Full vehicle servicing near Musaffah Shabiya to see if I should just take it back to the same place or get a second look elsewhere. Has anyone had a car feel worse after a service? And is it worth going back to complain or will they just tell me it's in my head? I don't want to be that customer but I also don't want to ignore something that might be a real issue.
