I dont have anything to monitor lean burn. I recently replaced the dist. and I never reset the ecu. I have no check engine light but codes 8 and 9 are stored. Im going to reset the ecu and see if that helps but I don't think it will. Car runs good, no odd issues. Literally just out of the blue decided to start getting crappy mileage and no shift light. I just cant think of what could be malfunctioning that controls the shift light but wouldnt cause a CEL. Map sensor? It used to give me a shift light from the minute I pull out of my driveway. Now even if I get the shift light working, I can turn the car off and start it right back up and no light again. Im stumped. I have found a few threads with similar issues as mine but never a solution. Anyone know what exactly the shift light runs off of? Im assuming the vss, tach signal, map sensor, temp sensor and .....?
