tdecker Posted March 1, 2005 Share Posted March 1, 2005 I'm new to this!! The check engine light is on and code 21 and 12 are coming up. It starts hard after it sits for a while but once its running its okay. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted March 1, 2005 Share Posted March 1, 2005 I'm assuming you have a first gen legacy 90-94 with MT. I would probably ignore code 12. The hard starting symptoms are analogous to a bad temp sensor, which is code 21. They can be had for about 20 bucks or so at www.1stsubaru.com I'd start with that and see how things work.
