I plan to take my 2001 Chevrolet Impala LS into the shop to get serviced. Here is the problems I have with it: Turn signals will randomly not work, Have to press the Hazard button several times to get them to work. Starts badly, The 1st initial start (from sitting in the garage) It starts just fine. Any minimal amount of driver (i.e half a mile to a store) and then turning the car off, coming back to start it it will crank and instantly shake and stall out. To fix this I have to give it gas the second it turns over and this has stopped working recently. Just yesterday the starting issue got worse, now when I start it it will make popping sounds then stall. It even shot smoke up from under the hood (but i found no source for it). I will have all of these problems addressed when i take it in, However I was wondering if any of you have had this problem on and GM and what the problem and cost of repair ended up being.
