Just looking for some help. I recently replaced both fuel filters and o rings after getting air bubbles in line. The air is gone.. but shortly there after I started getting the Engine Electronics Error message and glow plug light. The car sometimes runs rough on starting but quickly evens out.. other times it runs fine.... outdoor temp does not seem to be a factor. I have already cleaned the MAF..though I guess it could be bad. Also, does anyone know of anyway to pull the codes without a reader?? Thanks

auto zone should b able to pull the obd11 code.
