Hey all.. question for you. Got in my car yesterday, turned the key and it wouldn't start. It was cranking, but wouldn't fire up. After a minute or two, it started up very hesitantly, but then started rather violently revving itself from 600-4k very quickly. It was as if I was alternating slamming the gas and brake pedal. Went to drive it a bit and it just bogged completely down while revving away. Shut it off and let it sit, started up and got the same thing. Revved it myself in neutral... same thing. Just went back to low idle and high revs. Went on for about 10 minutes. Finally shut it off one last time, started up and it was perfectly fine... as if nothing happened.
Thoughts? I did a tune up 5k miles ago with new plugs and wires. No SES lights or codes.
