I have a 2004 ES330 with a hestitation problem. It is good from a full stop but like I go in the region of turns on onto highway ramps, later I sadden the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon as soon as the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery sufficiently charged? With or without headlights on. Relatively additional battery. Mechanic s Assistant: What is the model of your 04 Lexus? ES330 Mechanic s Assistant: Are you fixing your vehicle yourself? What have you tried appropriately far? I ve cleaned the MAF sensor. Checked for friends in the intake. in the same way as I put my Turbo OBDII app on, everything seems good except that the TPS stays constant a propos 30%. This is a drive-by-wire model appropriately it has not throttle cable or usual TPS. I take on the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know before I affix you? No, I guess that is it.

Its afterward worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a sick pump will all outcome in insufficient fuel subconscious delivered to the engine. Might in addition to be worth cleaning out the idle quickness control motor / valve as these get clogged stirring taking into account carbon and some brake cleaner washed through helps pardon things off.
Hello the TPS does have an effect upon switching the car into idle mode thus I'd suggest to make definite the throttle dish is 100% closed and not slightly ashore with carbon. and next accustom yourself the TPS consequently that the IDL fasten is continuous to the E2 attach behind the throttle is closed, and gain access to circuit afterward the throttle is just cracked. Don't distress very nearly any voltages, the IDL right of entry is the truly important one.
