03 Hyundai Accent check engine flashing????

Asked by Jan 27, 2015 at 08:37 PM about the 2003 Hyundai Accent

Question type: Maintenance & Repair

It's been a slow coming problem thats reoccurring. I took my car to get emissions done
and a cylinder three misfire came back and also the check engine light didn't work at all.
I took it in and had them check the bulb and it was obviously broken, got that fixed by
them because I didn't want to do it myself. They thought it was the coil pack, we changed
it, re gapped new spark plugs checked the wires etc. A slight change but the check engine
is still blinking. The battery is pretty old and corroded, I was thinking about changing it and
seeing if that was my reason for the loss of power, it also won't read on an OBD reader
whatsoever. Im going to check the fuses again, see if I mess around with those. I'm at a
loss and Im not going to keep throwing possible parts that MAY work at it and end up
spending more than the car is even worth at this point.

What I can tell you that when a CEL is flashing it indicates a more serious problem that a steady-on. And ECU's, computers don't like varying voltages, from things like battery connections, grounds, can cause problems

I changed the battery and everything seemed exactly like it should, engine light came off and the hard idle stopped. I drove it today to get my emissions done, filled it up and as I was IN LINE at emissions my check engine popped up, didn't blink just stayed on but it was still running fine. Im going to do a complete oil change because it needs it, see if it helps. I am really at a loss at this point. It definitely seems electrical, at least to me...
