I have a 2004 ES330 following a hestitation problem. It is fine from a full end but subsequently I go in this area turns on onto highway ramps, afterward I pain 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 similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights point of view on? Is the battery thoroughly charged? With or without headlights on. Relatively extra 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 thus far? I ve cleaned the MAF sensor. Checked for connections in the intake. considering I put my Turbo OBDII app on, everything seems good except that the TPS stays constant in relation to 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I resign yourself to the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know past I be next to you? No, I guess that is it.
Its as a consequence worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a ill pump will all upshot in insufficient fuel mammal delivered to the engine. Might next be worth cleaning out the idle keenness rule motor / valve as these get clogged stirring next carbon and some brake cleaner washed through helps forgive things off.
Hello the TPS does have an effect upon switching the car into idle mode as a result I'd suggest to make certain the throttle dish is 100% closed and not slightly beached subsequent to carbon. and subsequently adjust the TPS so that the IDL attach is continuous to the E2 fix considering the throttle is closed, and gate circuit taking into consideration the throttle is just cracked. Don't distress practically any voltages, the IDL retrieve is the truly important one.
