St205 Gt4 Turbo Problem

[Hot Hatch World]

Hi people,

I'm new here as you can see! I'm hoping you can help me out. I own a ST205 Celica GT4, and in the last few days the engine management light has come on, but there was no effect in performance what so ever, so I put it down to the fact that the car is in need of a service. (The next service is due at 90k, and the light came on at just over 90k.) Yesterday though the car seemed sluggish, and when I looked at the boost guage on the dash, it wasn't showing full boost. Before yesterday the needle going over the top of the guage, but now it only goes 3/4 of the way up it.

The car is completely standard except for a straight through exhaust. Any ideas what it could be? There was some oil on the back of the turbo, but I have wiped that off and there has been no more come back since, and I have checked the pipe coming of the top of the turbo, and there is a very small amount of oil in there, but notmuch at all.

Any ideas?

Thanks in advance

Matt
