Well I haven't had a CEL in ohhh forever. Did my regular maintence and cleaned out MAF with the CRC spray. How do I know if I need new O2 sensors?
One thing does bother me. When I'm in first gear and I let the car coast (foot off throttle) I get a fluttering sound, (like blowing on a sheet paper paper) coming from the engine. What's that all about?
