I get 3 flashes which is the map sensor on my CEL. When I start the car it drops to almost 0 and goes back and forth from 1 -0 rpm like 3-4 times and idles ad 1k rpm. I think my map sensor is bad so I am trying to buy one but can find any. I know that at the dealer and autoparts its going to be a lot so I searced on ebay and found mostly the jdm map sensor. are these going to work just the same as an oem one? thanks

 

just get a new or used throttle body with all working sensors, if you change any of the sensors TPS or MAP you will need to recalibrate it, and if you don't know how then you will have to bring it to a mechanic or the dealership. Save your self some $$ find a used throttle body with working sensors and call it a day.
