I dont know when it started happening or if it is just becauase the weather is cold but when ever i first start the car up and put it into gear and give it gas, it fells like its about to completely stall out and cut off, engine and electrical, because yesterday i was like screw it and give it alot of gas and the engine almost cut off and the headlights went off for a brief second. I dont know what to do to fix it. Ive had the exhaust system flushed and dont know what to do =/
