I have a 2004 ES330 following a hestitation problem. It is good from a full end but in the manner of I go in the region of turns on onto highway ramps, considering I sadden the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon like the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery adequately charged? With or without headlights on. Relatively further 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 hence far? I ve cleaned the MAF sensor. Checked for connections in the intake. later than I put my Turbo OBDII app on, everything seems good except that the TPS stays constant roughly 30%. This is a drive-by-wire model hence it has not throttle cable or normal TPS. I say you will the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know before I border you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. taking into account I unplug it and manage the motor, the car runs rough and at 850ish. I can abandoned guess that my other rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of all this. I don't think the tps has that much direct in the oscillate of rpm though? I think it isolated adjusts it in the region of 1k..
I'm reviewing your ask now, and will state incite behind your reply ASAP. Rgds Greg. What irregularity codes realize you have. Does the engine manage subsequent to the MAF disconnected. gone the loud hissing hermetic this could be your problem. This could be a large vacuum leak ,with the MAF aligned it is lonesome measuring the freshen that is getting similar to the MAF, thus if the intake manifold is sucking in freshen the freshen to fuel ratio will be extremely out and cause the engine to stal
