Air Flow Sensor Problem

Featured Replies

Hey, folks.

 

I have a 99 Impreza Outback Sport. Installed FACTORY cruise control last night. Cruise works great but all of a sudden the check engine lite comes on and the car won't idle. Discovered that if I disconnect the Air Flow Sensor on the air cleaner, the car will run. Still idles rough but will run.

 

Anybody ever have any experience with this type of thing?

 

Thanks In Advance,

So all you did was install the CC? What wiring did you have to modify to get the cruise installed?

 

 

 

Didn't modify any wiring as it is prewired from the factory. I was told that Subaru no longer makes cruise kit for 99 models but local dealer said dealer in New York had one sitting on the shelf so I called and the guy shipped it to me for $80.00!!! Was tired of it sitting around apparently. Looked at the instructions and thought I could do it myself. Cruise install went well but then car wouldn't idle properly. I did (per instructions) unhook the negative battery cable during install. Played with it all weekend and couldn't get the car to run with the Air Flow Sensor plugged in so unplugged it and drove to local dealer this morning.

 

The 'resealed' the air filter and basically cleared the trouble codes, plugged the Air Flow Sensor back in and it runs perfect. $48.00 bill...
