Hey guys i couldn't find much on this issue that just happened tonight. I drove my car to the local meet and parked it for about an hour or so. getting ready to leave. Fire up the car and i hear a loud bang and the car shuts off. Buddy yells smoke. I was confused. I tried it again same thing. I check all the hoses to the intake everythings fine. Start it again it runs. Idles fine. Check engine light appears. haven't checked the code yet but i turned the car off again. Started it and it didnt it again. About the 3rd time it started and ran fine. What could this be? I remember this happening when i was cleaning a couple months back and left one of the hoses disconnected but everything seems to be hooked up. My buddy said it could be a bad egr valve? where is that located if that could be it. I'll post codes in the morning. Any ideas would be helpful. Thanks
