So, my car this morning on the way in ran just fine, I went to the bank and as I pulled out of the office, the CEL came on, the car still runs great, smooth idle, consistent power, nothing out of the ordinary.

Bought a code reader and it says P-0300, 0303, & 0304. I understand that these are misfires on cylinders 3 & 4, but from my searches there's nothing conclusive as far as what to do next.

The CEL is not blinking, just constant.

Any help would be appreciated.

Mine did that and needed a valve adjustment... another symptom was that the power band wasn't very smooth... felt like it was hesitating from around 3K to 5K and then would open up again.

Thanks Alex. I'm going to take it in to the dealer on Monday, there's too many variables of what it could be, and I just don't have the time or know how to go about checking each and every one.

Hopefully it's something simple.

Mine is running just fine, so I'm not sure what's caused it.

hope things work out for your baby Sam. Surely keep us updated on what happens. I was already thinking about getting my valves adjusted (not sure how often its supposed to be done but my car turns 6 in December and has 73,xxx on it), but I worry about anyone touching my car lol.

Certainly will Marc

I was thinking the other day how well the Honda has done over the course of 4 years, but then again it's only got 30k on it. I guess I jinxed myself

I would just reset the ECU and see if it comes back.

Is it okay to do that? I read in "under the hood" not to do that.

I unplugged the fuse for about 30 secs or so and the CEL came on as it did before.
