Put some up the vacuum line on the fuel pressure regulator, it runs much smoother now, but the check engine light is on. Will this go away? Do I need to reset anything? Thanks for any help.

check what code it is, then post it and maybe we can help out.

post the code - could be something actually failed at same time - or reset the code/ecu and see if it comes right back

So how do I reset the code/ecu, just disconnect the battery for a couple of minutes right? I was planning on stopping at checker on my way home today if it's still on and have them read it. When I get the code I'll post it.

You can check the code yourself without a machine. Check the FAQ

Yeah I know I can, it's easier for me to have them take a minute and check it for me.

I reset the ECU and now no check engine light.

Well, when you reset the ECU it temporarily clears the CEL but if something is wrong it will trigger again; it usually take a set number of cycles before it will trigger. I hope it doesn't come back but just because you reset the ECU doesn't mean the problem is solved. Good luck.

It was probably just a miss fire code from the seafoam.
