I have a 2004 ES330 gone a hestitation problem. It is fine from a full end but following I go a propos turns upon onto highway ramps, behind I upset the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon like the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery adequately charged? With or without headlights on. Relatively further battery.

I don't think the tps has that much govern in the alternative of rpm though? I think it unaided adjusts it roughly speaking 1k..

Does the engine control past the MAF disconnected. following the noisy hissing unassailable this could be your problem. This could be a large vacuum leak ,with the MAF related it is by yourself measuring the expose that is getting taking into consideration the MAF, suitably if the intake manifold is sucking in ventilate the expose to fuel ratio will be utterly out and cause the engine to stal
