Legacy777 Posted June 26, 2005 Share Posted June 26, 2005 Did they blead all the air out of the radiator when they serviced it? Did they replace the thermostat? It may be worth resetting the ECU. If it saw some very high temps, the long term fuel trim memory might have gotten screwed up. Quote Link to comment Share on other sites More sharing options...

Legacy777 Posted June 27, 2005 Share Posted June 27, 2005 The ECU is the computer for the car that runs all the engine management. Here's a pic of where it's located (remember it'd be on the opposite side since you have a RHD car) http://www.main.experiencetherave.com:8080/subaru/images/ecuhide.jpg Another scan http://www.surrealmirage.com/subaru/files/swap/elect_unit_loc/6-3_electrical_unit_location05.jpg Instructions to reset the ECU are on my site under notes & tips, engine related.

Cougar Posted June 27, 2005 Share Posted June 27, 2005 I assume you have checked the ignition area for any problems. If not, I would do some checking on those items. Also check the fuel filter. Quote Link to comment Share on other sites More sharing options...
