I have a 2004 ES330 with a hestitation problem. It is good from a full stop but later I go as regards turns on onto highway ramps, similar to I distress the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon subsequently the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery abundantly charged? With or without headlights on. Relatively new battery. Mechanic s Assistant: What is the model of your 04 Lexus?

Checked for associates in the intake. bearing in mind I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant in this area 30%.
