Since few days I noticed smthng not running normal in the morning when I start my engine. Earlier.. mean when I bought the car till I noticed this change these few days,when I put the start, the engine rev at 1500 rpm then come down to 1000rpm, It's normal because as cold it shud warm up, but now I start the engine this morning, it reve only at 700rpm.. have to wait 10 mins before it got it's normal temp.. sure it's not normal and sometimes it turn off by itself due to low rpm.. I think it's got something to do wiz an idling valve or something liike that? anyone can answer me please
