I have a 2004 ES330 next a hestitation problem. It is good from a full end but following I go roughly turns upon onto highway ramps, later than I afflict 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 with the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery fully charged? With or without headlights on. Relatively supplementary 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. taking into account I put my Turbo OBDII app on, anything seems good except that the TPS stays constant re 30%. This is a drive-by-wire model appropriately it has not throttle cable or usual TPS. I undertake the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know before I be close to you? No, I guess that is it.
Its as well as worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a below par pump will all result in insufficient fuel innate delivered to the engine. Might as a consequence be worth cleaning out the idle swiftness run motor / valve as these acquire clogged taking place taking into account carbon and some brake cleaner washed through helps release things off.
Hello the TPS does have an effect upon switching the car into idle mode in view of that I'd recommend to create distinct the throttle dish is 100% closed and not slightly stranded afterward carbon. and next acclimatize the TPS hence that the IDL glue is continuous to the E2 glue as soon as the throttle is closed, and get into circuit subsequently the throttle is just cracked. Don't bother more or less any voltages, the IDL get into is the essentially important one.
