Shuddering when engine is warm and gets worse after driving. Ridles ruff to when hot. Give a little throttle and it shutters all the time, no check engine light on, decreased power slow to pick-up speed. Thanks bruno

Have you checked fuel pump pressrue and also, have you checked the catalytic converter to see if it plugged? When was the last tune up?

The fuel pressure is low which can cause power loss. As far as the converter, see if there are any noises such as ratteling, hissing. Noises coming from it with the engine on. When the engine is hot, check it to see if it is red hot. Also, feel if there is ample pressure coming from the tail pipe.

Let me know.
