I went to get my coupes smog/registration done this morning and go a "not ready" result proably because I had to recently replace the battery. I plugged in my OBD and went for a 130 mile drive but its still showing no ready on the OBD. The dealer said it needs to be driven for several days through multiple heat cycles and in a varying dtiving conditions before the ECM will collect enough information to be in "ready" condition. Anyone else deal with this? Current tags are up Friday.
