My Cadillac has been to the dealership and to transmission specialist and both say they don't know what's wrong. No codes besides the security light on the dash that comes on every now and then. I can't accelerate around a bend at all. I changed the spark plugs ,fuel filter ,air element is dirty little. I checked my fuel pressure at the schroeder valve and that seems to be fine. I been reading the chilton Manuel that I have and still don't know. I was thinking maybe the catalytic converter maybe?? Or maybe the spark plug wires??
Bad Gas maybe? The N* needs its octane.
I'm rather surprised that a Caddy dealership couldn't diagnose the problem!
They would have checked all the obvious things like fuel pressure, exhaust backpressure, air filter etc.

I have never heard of this in the Sevilles, but it is common in the early '90s Devilles. The tank baffles come loose and when in a turn (with less than 1/4 tank of fuel) centrifugal force sloshes the fuel to one side, the pump sucks air and the engine starves out.
Getting worse by the week it seems?. I don't know if it's the TPS or intake manifold leak. If I drive slow its ok. I took it to the dealership caddy and they said mystery problem they don't know where to start. Aamco tranny specialist said no codes couldn't find anything other than I need new back brakes and I have a bent front right axle so I took care of that. They thought that a bent front right rim could cause that but I rotated the tires and same thing. I changed out fuel filter gas pressure at railing is good new spark plugs don't know what could make my car shudder like that. Also around a bend I can't accelerate or the shudder occurs ???
