About every 3-4 weeks I keep getting CK. engine light, fault code(s) Misfire on Cyl 1 & 3? New plugs NGK and wires were replaced. Power and performace are good, fuel milage is around 21- 22 mpg.

DerFahrer Posted December 28, 2003 Share Posted December 28, 2003 Check the coilpack, that's probably headed south... Subarus have never had good gas mileage. My opinion is that they're set to run a bit rich from the factory, just for safe-keeping... But this is a great place to get help, lots of knowledgeable people here. Welcome! :cool: Quote Link to comment Share on other sites More sharing options...
DWM650 Posted December 28, 2003 Author Share Posted December 28, 2003 Thanx's for the reply. It defiantly has an interment skip at idle, more when cold. also a bit of a hesataion if you snap the throttle quick anytime. DaveyMac:eh: Quote Link to comment Share on other sites More sharing options...

I average 25, and I have a "lead foot". Quote Link to comment Share on other sites More sharing options...
DWM650 Posted December 28, 2003 Author Share Posted December 28, 2003 Originally posted by myles I'd check the wires and coil pack. Already replaced wires with plugs. Ordered coil pack today. will have it Wed. 12/30 I'l post back with results. BTW how do I know what Generation Motor do I have???

Commuter Posted December 28, 2003 Share Posted December 28, 2003 Unless you have a very rare beast, you will have a Phase I DOHC engine. The SOHC engine was not put in the Legacy's until the 2000 model year. The difference is obvious if you have seen both engines. The DOHC has larger front engine covers with 2 circular 'marks' per side (ends of camshafts). Also, since you've been at the spark plugs just recently - The DOHC's spark plugs go in horizontally. The SOHC's plugs are on a slight angle from above. Commuter Quote Link to comment Share on other sites More sharing options...

DWM650 Posted December 30, 2003 Author Share Posted December 30, 2003 PO301, CYL 1 MISFIRE DETECTED PO303, CYL 3 MISFIRE DETECTED Warmed up engine after it sits for 5min, and then restarted and allowed to idle. You feel the engine skip and shake just before it produces codes and CEL comes on. Ya also can here it miss at the tail pipe.
