Anyone out there used a 'CREADER' OBD II code scanner? My '00 Chrysler Voyager got a bad tank of gas on Saturday. It's been hesitating and stumbling since then and as of yesterday, the check engine light came on. It stumbles a little bit at idle, and minimally at light load cruising. It flashes if I accelerate briskly or put a load on it when cruising. When I got the oil changed today, the dealer kindly offered to charge me to read the car, which I refused. If I'm going to pay to get the codes out of my car, I'd rather invest it in a tool like this. Anyone have personal experience, thoughts about this and other OBD II readers, such as EQUUS, Actron or others?
