Big Pop

[93Notchback93]

i started my car today and I gave it a little rev to like 2000-3000 rpm I heard a big loud pop I don't know if it came from the exhaust or the engine. I turned the car off after that and haven't started yet. Thought I'd post and get some feedback

backfire through intake or exhaust?

Might be signs of running lean. Run the codes

Dump codes sticky.
Look at the top of the 5.0 Tech forum where the sticky threads are posted. One of them is how to dump the computer codes. I highly suggest that you read it and follow the instructions to dump the codes.
