Check your coolant temp sensor. If it is unplugged or the connection is damaged in any way, it will default to full time fan and your fuel mixture will go full rich. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
