Injector Sensor code after fill up
 

On my '99 Accent, everything has been running just fine. I filled up on gas the other day, and right when I started it after, I noticed it was missing. :eek: So I ran a scan, and I'm getting Injector Circuit/Open on cylinder 2.

I previously had a bunch of charcoal in the canister (common problem with Hyundais, with the slow fill up, etc.) About a month ago, I opened that up to see if was what folks often report, and it all dumped out. It's been totally fine since then. Not sure if that's related, but I thought I'd mention it.

Not related. And open circuit problem is an electrical issue. The injector is probably bad.

Yeah, it's the injector. I swapped the two middle ones to test. Now it comes up as injector circuit for cylinder 4. Just a coincidence, I guess. I ordered a replacement

So... which one is 4? I'm having a hard time figuring out the cylinder order. I was thinking I was swapping 2 and 3. But one has to be 4. Which one is it?

What engine? SOHC or DOHC?

2nd image. DOHC then?

Got it figured out either way. New injector came in, so I put it in the 2nd one from the left. I figured that couldn't be number 2 because... well I had a some logical reason but I forgot now. :)

And wow, what a difference in power! Way more than even before it started missing.

The second image is the SOHC and the second cylinder from the left is the #2 cylinder.
