Is it normal for our cars to feel sluggish after a few weeks of normal driving? My car felt much more responsive a few weeks ago. Everything is up to par with its maintenance and tune up. But for some reason, it feels sluggish lately. Throttle response is a little weak and car don’t pull like it used to. Any ideas?

could be a vacuum leak, check the vaccum lines

Is there a certain to do boost leak test on these cars? I've done it many times on other cars but trying to see if there are any tips or anything I need to watch out for when doing it. Thanks

I just do the latex glove over the oil filler cap check. If it fills there's a leak and if it doesn't you're good.

Woah, never heard that before and I been working on cars for like 20 years. Sounds like a much easier way to do a quick check. Care to elaborate?

Do you keep oil cap off or on? Put a glove on and idle car? See if it inflates?
