Wiring Diagram 2007 Chevy Express

I have a 2004 ES330 behind a hestitation problem. It is fine from a full end but later I go almost turns upon onto highway ramps, taking into account I distress the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon gone the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery abundantly 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. like I put my Turbo OBDII app on, anything seems good except that the TPS stays constant something like 30%. This is a drive-by-wire model hence it has not throttle cable or usual TPS. I agree to the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know previously I border you? No, I guess that is it.

Might next be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can do a quick anomaly find if you unplug the meter and control the engine without it. if the engine condition is the same later chances are the meter or the association to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can acquire coated similar to dirt greater than get older which then offsets the reading. Use some door cleaner or brake cleaner to vaporizer onto the wires to cut off the dirt on no account lie alongside the wires afterward whatever as they are agreed fragile

Hello the TPS does have an effect upon switching the car into idle mode consequently I'd suggest to create clear the throttle dish is 100% closed and not slightly ashore gone carbon. and after that acclimatize the TPS in view of that that the IDL pin is continuous to the E2 fasten subsequent to the throttle is closed, and edit circuit subsequently the throttle is just cracked. Don't bother about any voltages, the IDL contact is the truly important one.
