Hi Everyone!
New 1999 mx-5 owner here and I LOVE the miata! got it about 2 weeks ago and just love how it handles and rides. Came from a 1995 dodge stealth R/T to this and love it every bit.
I bought this vehicle 2 weeks back and I am in the process to fix some of the minor issues (related to handling and suspension, changed front tires, found out that the front driver side shock was leaking so replacing the pair and also replacing all the brakes). Today on driving from home to work my Check engine light came on. I took it to an auto store here and they told me the code was p0172.
I have been reading about this and it seems that this could be caused by a few different things. I dont have any hesitation or lagging. My car doesnt stall. I do have a bit of rough idle at around 800 rpm (the car just jitters a bit but it is like that on every stop or when i start the car). Cold start RPM is around 1200 then it goes down to 800.
I was wondering if someone would have any idea about this? the car is stock but it does have a K&N Air filter (cone shaped).
Thanks you
