Alright so I bought the vehicle not knowing what I was getting into but a good friend of mine told me that it is an amazing fun car. So I bought it and fell in love with it. The car ran perfectly for the first two months. For the last week though it has began to idle a little low then when my friend test drove it sunday it shot out a check engine light, and the boost was not kicking in, which it hasn't done. Before getting it checked him and my other friend both said the same thing in the parking lot, it is running really rich, and to get the spark plugs changed and maybe the coils. I did that and the check engine light turned off. BUT now my turbo is not kicking in at all, after I did the spark and coil changes I drove it and the turbo was hesitating for the first 4 miles like it was hitting a wall, I called my friend he said to not take it into boost and just drive it conservatively till we figure out what is going on. I Then drove it today and the turbo is not working at all. I'm driving conservatively but I just wanted to see if it might have been just a fluke but no it is just not zoom zooming... Any ideas on what it might be. After the spark and coil change the vehicle felt 100 times better too but the boost is just not going. Also I am not very knowledgable about cars want to begin to learn more about them but for this time just explain each aspect of possible problems that way I can at least have an idea. As far as I know though everything in the engine is stock nothing has been added. Please help!! I love this car so far and don't want to drive just another car but a fun vehicle. Thank you for anything y'all can help me with.
