I have a 2004 ES330 subsequent to a hestitation problem. It is good from a full stop but similar to I go approaching turns upon onto highway ramps, following I distress 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 behind the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights point 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 therefore far? I ve cleaned the MAF sensor. Checked for links in the intake. like I put my Turbo OBDII app on, anything seems good except that the TPS stays constant with reference to 30%. This is a drive-by-wire model thus it has not throttle cable or normal TPS. I assume the TPS is integrated considering the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know in the past I attach 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 not a hundred percent pump will all consequences in insufficient fuel being delivered to the engine. Might plus be worth cleaning out the idle readiness control motor / valve as these acquire clogged up later carbon and some brake cleaner washed through helps clear things off.
Hello the TPS does have an effect upon switching the car into idle mode consequently I'd recommend to make clear the throttle dish is 100% closed and not slightly beached as soon as carbon. and subsequently acclimatize the TPS in view of that that the IDL glue is continuous to the E2 attach behind the throttle is closed, and edit circuit behind the throttle is just cracked. Don't worry approximately any voltages, the IDL open is the essentially important one.
