What's up fellow Hyundai owners. I'm having a problem and want to get some opinions on where to continue looking. A couple of weeks ago I don't have as much power under hard acceleration as before . I also get a similar noise as to what we get with cold starts, As if there's air escaping from somewhere. (Not the sound from the BOV after letting off) it's constant while under harder than normal acceleration. I still have some boost just not as much as before. Anyone know a good starting point to start looking for an issue? I just pulled the air box and intake and no obvious cracks in the plastic and filter is good. Thanks!
