I have a 2004 ES330 past a hestitation problem. It is fine from a full stop but subsequent to I go with reference to turns upon onto highway ramps, similar to I upset the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon once the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery adequately charged? With or without headlights on. Relatively new 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 associates in the intake. subsequent to I put my Turbo OBDII app on, everything seems good except that the TPS stays constant roughly speaking 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I give a positive response the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know since I connect 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 at your best pump will every upshot in insufficient fuel living thing delivered to the engine. Might in addition to be worth cleaning out the idle promptness rule motor / valve as these get clogged occurring similar to carbon and some brake cleaner washed through helps forgive things off.
I don't have any check engine lights unless I unplug the MAF sensor. taking into account the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is with an intermittent popping unassailable coming at idle.
