Cold Starting Check Engine light
I looked through a lot of the threads and think I have this nailed down but wanted to make sure. I have a '93 4 cylinder that is normally really faithful, even in cold weather. This Ohio winter has been rough and now I have to wait for the check engine light to turn on before starting. Once it comes on (sometimes over 5 min) it starts right up. Also, not sure if this is related but my gas mileage went south as well.
I checked all the spark plugs and everything looked good.
New fuel filter but no help.
Was thinking it might be the CPU??:confused:
Well, after doing more research, I'm going to try replacing the capacitors in the PCM. Hopefully this takes care of it.
