(Pre-context: I just bought my fiesta no that long ago and it only has 4200 on it, i did a sound Symposer delete and I straight piped it from the cat back) I was driving regularly in fourth gear and all of a sudden my engine was just revving and not accelerating. It would just keep revving and wouldn’t allow me to move very far once I made it to a stoplight. Now the clutch pedal feels heavier and I’m smelling fumes coming from the engine bay. Can anyone help me find out what is going on?
