Since the switch (over a year ago) when running Exxon, I have only had it happen once when filling up at an unfamiliar gas station. Since then, I have only had a handful and two were on the same tank from a Shell station I filled up at when I was low on fuel. I went 8 months before having another episode. All summer blends have ethanol, but they supposedly have the least and some research claims that they have minimal to none in their winter blends. Apparently, they use the least amount of ethanol in their fuel. I was using Chevron and Shell exclusively, but the service manager (been a customer of his for 20 years) said try Exxon. He stated that they had seen this on a couple of other LS engines (camaros and corvettes) He suggested switching gasoline. He said they found no codes, but ran an ethanol test on the gasoline and it came in at 9%. I finally had my dealer look at it when it went in for a bad Onstar sensor in the mirror (3000 miles). The subsequent starts and drives were uneventful. It would fire immediately and then die (run for about half a second). I started noticing that it happened warm, cold, or during an intermittent stop. I bought my ZL1 new two years ago and it now has 20,000 miles. Does the car run for a full second? Two seconds maybe? Does it actually start? Or just turn over with fuel and never actually stay for a bit? It most likely wont' show anything but if the car does it while they have it then they can fix it.Ĭould be anything. I'd take it to the dealer and just have them perform a test. But I've done that and not got a code before. You can start your car and let it idle with no MAF at all. So the fact that there is no code is already an oddity. If you think about it, your car dying like that should send a code anyway. But since it dies so quickly and then starts back up no problems, it's possible that the code is not sent. ![]() Those arent really the same as you are describing anyway. If your car is newer, then it woudnt' have the same early issues. Good idea, but wouldn't a MAF throw a code? Have you seen lots of MAF issues w/o codes? I doubt they'd replace that w/o one, unless there's a way to independently test the MAF, do you know of a way to do this? The car has maybe 4500 miles on it now.Īny ideas? Because of the intermittent occurrence, I really don't want to take it to the dealer w/o a thrown code, they'll most definitely have the thing forever and it'll never happen. Not like *right after/same day*, but still it never happened before that and started about a few days later. This started after my first service 3300 miles the dealership). Engine temp doesn't seem to be a factor (happens hot or cold), and time since being driven doesn't seem to be a factor (It's happened first startup in the morning as well as after a long run and only being off for 5 mins). Some more details: Yes, clutch is to the floor. It's never done this twice in a row, always after the start/die, it starts up and runs fine. After that happens, I start it up again and the car runs fine. About once/twice a week, I go to start the Camaro, it starts, runs for maybe 1 second, then dies. I'm a new member, I've been reading this site since ordering my Camaro in Jan, thanks for making such a great resource available! I've searched and can't find this topic covered yet, but I hope one of y'all have seen this before:įirst, it's a totally stock 2011 LS3 (I haven't done anything but wash it).
