Hi all, I recently acquired a Subaru Legacy 1991 RS. The car had been sitting for 7 years in a shed, but needed little coaxing to get going again. Ive had it on the road and warranted for a couple months now. She actually runs really well with no noises, and the clutch and gearbox are PERFECT, best ive ever driven. Zero rust dents etc. Ok now the bad things. Since I got her, when on boost (she boosts hard and all the way to red line apart from this) she will jerk or buck slightly a few times, but I can still keep my foot planted and boost hard. Ive put up with this since getting her as I dont know what it is. But more recently, she has aqcuired a new problem (related, unrelated?). She will only start intermittantly. I go out to the car and crank it over, but no go. Its about half the time. The other half the time, she fires after 1 or 2 cranks idles perfect. I have to leave it for anywhere between an hour, to the next day, and try again and it fires right up. Also once while driving, halfway thorugh doin a U Turn, it just cut out. I was on the fuel light so thought it ran outta gas. We put lots of petrol in but still no go. I went back to it a couple days later with all my tools, but alas I didnt need to do anything. She fired right up and I was able to use her as normal for a couple days. But yesterday I went outside to start her up and no go. Just cranking.
Please HELP
