Hi everybody. i have a problem with my honda element...the engine vibrates when idle and my car runs very slow. after i pass around 20-40 mph, the problem goes away. my car also has a starting problem, sometimes it takes around 5 secs to start. could someone help me? thx in advance.

Hi...check the spark plugs and the coils first.

thank you for your help, hondamania.
yes, you're right. i went to the mechanic yesterday. he told me, my problems including sprak plugs, coils and starter. i would change them as soon as possible. again many thanks.

Could also be bad gas !
