Problems while idling

[thepik]

Hey guys,

Recent I got a 2004 Mazda 3 with 74,000 KM.

Over the past few days I realized while I am at a red light or stop sign the cars rpms hover just under 1000 (maybe 7-800 and sometimes around 5-600) and it sort of starts to shake and run rough.

During drive its fine and idling while in park seems to be fine although I haven't really monitored it.

Thanks
Shawn

i would suggest cleaning the throttle body or getting it cleaned. its easy enough to do if youre up to it.

there are how to's somewhere on here, ill try and find some

also, check your engine mounts. one of them might be bad

EDIT

Check engine mount on passenger side, see if oil is leaking out..if yea, replace mount.
