Hi, it's not about Nissan but Mazda; I have both Nissan and Mazda and I have no place to ask about Mazda though...
I noticed my 88 Mazda 323 turns her check engine light while idling long time enough (maybe 10 mins?)... it is not always and I saw this happened twice until today - the first one 3 weeks ago, and the last one today. I started engine went back to my apartment, and then came back to find the light on. I just stopped the engine and re-started engine again - the light goes away.
Could it have something to do with cooling system? it takes a little bit long to reach normal temperature ever since I replaced radiator cap - actually it puzzled me but I didn't care.
any idea,please let me know. Thank you in advance for your help!
