No power when warm

[toystore]

Car runs perfect when cold, as soon as it reaches operating temp it falls flat on it's face. Tried O2 sensor, no difference, removed catalytic converter still no difference. Shows boost on factory gauge. part throttle tip in is responsive, then it's like you pull a parachute.

Is your clutch bad? What about a boost leak? Are you not getting fuel? So many questions.

Is it possible to have a boost leak when the car is warm, and not when it is cold ? Instinct feels like a fuel problem , however I still want to know why it's only at operating temp, and it is an automatic.

Test/replace coolant temp sensor for the ECU (not one for gauge). Faulty ones will continually tell the ECU it's cold so ECU will improperly set fuel rich.
