First off, it's a 4 cyl '04 accord, and this issue is super hit and miss. I can drive the car and it'll do it, then the next time I drive my car it runs perfectly fine. Whats more, the check engine light comes on roughly when the issue occurs, but then it'll turn back off later. It just keeps going back and forth like this. I noticed my battery posts were pretty dirty about a month ago so cleaned them off, but that didn't really help much.
Anyways, the issue is that as I drive around the electronics seem to stutter a bit. Like the radio will shut off for half a second then back on, the gauges all drop down like that also, and I can feel my power brakes stutter with it also, but only for a flash. Mechanically, the cars fine imo. So what could it be? My first thought is probably the computer's going, or perhaps a bad ground wire somewhere, but I don't know anything about cars beyond the basic mechanics. Common sense tells me the first thing would be to plug a reader into the car to read the engine code, can I do that even after the light is off (pull the most recent error)? Is it worth buying the reader, or is it just cheaper to go to the garage? (I've heard both ways).
