Picked up my first 1995 Celica GT today and after driving it for awhile it really seems to fall on it's face after about 5000RPM.........any ideas why it's doing that? Fuel pump? Bad intake? Injectors? First thing tomorrow I'm removing the intake and cleaning the TB and the intake filter and then a full tank of 93 octane. I'll probably check the spark plugs/gaps while I'm in there, anyone know what the stock gap should be? Only mods it has are a DIY intake and a full catback exhaust.

Running a higher octane fuel won't do anything for power. It just keeps the fuel from detonating too soon, which keeps the engine from knocking. It's useless unless your engine is high compression or boosted. A stock 5S will do fine on regular fuel and save you ~$5 per fill-up. The 5S is definitely not a performance motor. Just an economy engine that happens to take to boost well. (Hint hint.)
