When my engine gets warmed up (after about 10-15 min.) it starts running like crap!! it starts lunging and i get a loss of power. i have coil on plugs if that makes a difference. it is a 92, it has twin cams 24 valve, V6 3000 engine. if you know anything about this please help!!

 

Clean the red water temp sensor connector. It's very near the fuel pressure regulator
