I have a chevy camaro with a 5.7 liter motor in it and when I first start it it runs fine. Once it warms up a little the engine will start to surge at idle and become hesitant upon acceleration. Sometimes it will even die at an idle. I have gone through and checked the tps sensor and checked the timing but still having the problem. Any advice?
