When you first start and go it acts like injectors are clogged but runns fine afterwards. Runs like injectors are clogged after just having oil changed switched from 10w 30 to 5w 30 because they said dealer recommended it but the very next day is when it started acting up when it was cold thought it was bad gas but run it all out and added complete fuel system cleaner and put new gas in but still does the same but when car warms up good it runs fine like nothing is wrong no black smoke out the exhaust or anything like that either
