I have a 94 LX that won't idle down afer warmup, stays at 1600 RPM. The check engine light is also on, probably related. How do I pull the engine codes from the computer? Probably the IAC switch?

Thanks.

 

their is a two pin plug pass.side(usually blue) you need to short and count the blinks use the search button i have seen the code counting somewhere.

 

under the glove box there is a blue connector, use a paper clip to jump the two sides of the blue connector, count how many long, and how many short blinks the check engine light blinks when you turn the key to acc, the long blinks are the 10's the short blinks and the 1's.. then look up online to find what the code means.. or just ask here and im sure someone will tell you

 

You need a list of the engine codes, i'm sure its on here if you search.
