Default Rough idle after flooring it? 1999 SC2

I gunned my car when I was pulling across the road into a friends driveway and noticed it idled rough (Felt like it was misfiring) for a minute or so after that. After I drove it not even a mile it was running just fine. Why would it have done that? ECTS is brass btw.

Sounds like you may have burned an exhaust valve.

How many miles on the car, and how many miles are on the fuel filter?

Just about to hit 131,000 and not sure about the filter. It's the first time it's idled like that after flooring it. I've had to do that before pulling into traffic on the highway and it's never idled rough after that. Like I said it only idled rough for maybe 30 seconds to a minute then it was fine. Wouldn't a burned exhaust valve make it run rough all the time?

nope, just at idle. unless you've got more serious stuff going on. but meantime, check the normal tune-up items: wires and non-platinum plugs to start

Yeah, I was going to check the plugs and wires before winter. The plugs only have about 10,000 on them though but they ARE the cheap copper ones so I don't know how long they'd last. Not sure about the wires, haven't replaced them yet.

Would there be a way to test for a burned valve without having to tear the motor apart?

Then I wouldn't worry about it. Just replace the fuel filter so you don't burn a valve next time.

if you're replacing the fuel filter make sure you go with OEM or NAPA/WIX. this is one thing you do NOT want to skimp on.
