1990 300te fault code
 

Please Help,
My check engine like came on. I checked the codes and got the light to flash 18 times. I then reset it, drove the car around and the light has not come back on. What code was it? should I be worried? Will it come back on at random times? What should I do to fix the problem? Thanks in advance,

Chris

Idle air valve?

As far as I remember. It's been quite a while..

Code 18 is related to current flow from the CIS-E computer to the idle valve.

Thank you for the replies, what would cause this code? and what should I do about it? Is it something that has to be done at a shop, or is it feasable to take care of it at home? Thanks

Chris
