Whats up everybody.

So I am wondering if any other new Xb owners are experiencing anything like the rough idle issue I have. If not, any insight would be apperciated.

My problem is this, when my xb reaches its low idle of 500 RPM I get a really rough sound from the engine. The idle sound is bad enough to resonate quite loudly in the cabin and can be heard even above music playing at 20-25 volume.

At first I thought the sound only happened in the early morning when the engine was cold but then I noticed it happening last night at stops, parking, ect (but again only at the 500-550 rpm mark).

Anyone know what this could be/seriousness/if I should have it looked at? Please let me know.

Thanks

P.S. I have read aout the hood vibration issue some have had. This is definitely not the problem. (I have opened the hood and listened to the idle)

how many miles ya got?

mine did it for a little while... then i fixed the hood like you said.. and it helped. then after about 1000 miles it stoped all together... unless maybe you have the A/C on ... all 4 cy's do that!!

i changed to synthetic oil and my rough idle was gone. Plus my oil was a very dark red when i changed it, almost black, nasty....Now that i changed it, magic, no more rough idle.

Yea, odo is sitting at about 800 miles right now. I figure if I can get some time after the Thanksgiving holiday I will get it looked at.

The problem is not related to the AC being on. I dont think ive ever even used it .
