I'm GTHunter429. Recently bought my first Honda. A 1990 Accord LX. Great running car but with a few kinks. The green s light on the dash stayed on constantly and the temp gauge did not work. I installed an add on gauge, and unplugging the factory sensor caused the check engine light to come on. After doing it, the green s dash light now flashes constantly. None of these factors have affected the performance. It runs like a raped ape and shifts normally, but seems to be stuck in sport mode. What do I do? If any one can offer some helpful advice, please do. Thanks.
