Hi all,

Can anyone give any possible reasons for the following,
The cars a 93 wrx, around town the afr meter works perfectly and is blue from about half throttle to WOT, as soon as i go on a motorway type drive the meter stops working completely and will not light up at all until i restart the car after it has cooled.

Any help appreciated

Cheers Lee

 

THANKS

 

had the same problem on my wrx, the lambda sensor is buggered!

fitted a new one and problem solved.

also improved MPG too!!!

 

Cheers
