Got an 87 Subaru GL, 4WD, 1.8 (non-turbo) carburated.
I got it running now, but at low RPM's, it has pretty much no power. The idle fluctuates between about 400 - 1000 RPM when its just sitting.
At high speeds, it seems to run fine. Once I get it up to about 3000 RPM's, or about 40 - 45 mph, it does okay, still not perfect, but it doesnt act like its gonna die or anything.
I have had about 3 people look at it, and nobody can figure it out, small town, and there are virtually no Subaru's in this town. Nobody has ever really worked on one.
The carb backfires too, especially after it is reved up to a high RPM, then as it is coming down, it pops out of the carb, and almost immediately dies.
We have checked the timing, seems to be right on, new plugs, cap + rotor. Wires are okay too.
Anyone have an idea? I put a new fuel pump on too, wondered if the pressure of the new pump was too high, could this cause it? The fuel system runs stock about 2.2 - 3.3 lbs of pressure, and the new pump I put on pumps 4 lbs. Would this make a difference?
Someone please, HELP ME!!!
If somethinks they know, they could also just take the car home for $350. There are some pics on this thread, and I can take as many more as anyone wants.
