December 28, 200322 yr Hello everone Im new to your board. Glad I found it ! I have a 99 OBW, 95K on it. 5 speed trans. 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. I think it this poor? Anyone have a suggestion were to start? DaveyMac
December 28, 200322 yr 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:
December 28, 200322 yr Author 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:

I average 25, and I have a "lead foot".
December 28, 200322 yr Author 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??? DaveyMac
December 28, 200322 yr 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
December 29, 200322 yr what error code are you receiving? get the code ## and i can maybe shed a little more light into what's going on.... jamie
December 30, 200322 yr Author 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. Daveymac ":cornfuzz: ps, this is random "not all the time"
