SF5 Hesitation
Hi everyone. I've haven't owned a Subaru for a couple years, but just got an '01 SF5 STi out of Japan.
Driving it back from Vancouver last week right away I noticed a sputter/hesitation under load. As I'd roll into the throttle and the boost would build, it would start to buck pretty bad.I basically babied it all the way back to Saskatoon, as I could mostly avoid the problem if I was really gentle with it. So far I've done a Seafoam treatment in the fuel, and changed the fuel filter. Neither have eliminated the problem. I've had someone tell me it could be the fuel pressure regulator, that was going to be next on my list.
Thoughts?
