I'm a new 03 coupe EX-L owner with about 5000k. I'm noticing that when decelerating or coasting without applying the gas the engine vibrates always at around the 2100rpm mark and at no other spot. It happens in 2, 3, 4 and 5 gear. It's almost a 'rough' spot thats consistant. Is this part of the break-in period and it eventually goes away? Other than this the idle and acceleration are smooth

 

No, get your car checked b4 it gets worse...

Not like you have to pay its under warantee, just have them check it, you should ge a free rental and all...
