97 SSE Will not run

[97BonnevilleSSE]

Weird new problem came up. It was driving normally when I came home from work and washed it. 30 minutes later I started it, and it will start and run for about 2 seconds, then dies. I tried again this morning, same issue. If I start it and then apply throttle, it will stay running at around 2K rpm. But when I let off it dies again immediately. Car normally runs fine. What could be the cause? Thanks.

One other fact I forgot to mention:
Prior to washing it, I raised the hood and blew out the cowl vents with a leaf blower. I can't see any loose connections/vacuum lines, but there is that. The blower/car wash may be unrelated to the problem, but I can't think of any other factors that changed.

Do you have a check engine light on when it is running?

Yes, it stays on. I still have a random misfire (injector) that throws a code. I haven't scanned it in a while.

I went back out after lunch and tried it again, on a whim. It started up and idled like normal. I drove it around for about 15 mins and it ran totally normal. I hate when problems magically fix themselves, but glad its running.

Did you recheck for codes?

I did not, but I will.
