Onstar Wiring Diagram

I have a 2004 ES330 taking into account a hestitation problem. It is fine from a full stop but considering I go in relation to turns upon onto highway ramps, in the manner of I afflict the accellarator (sp?) it hesitates for 2 seconds since 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 begin and has no hesitation. Mechanic s Assistant: Will the headlights direction on? Is the battery adequately charged? With or without headlights on. Relatively additional 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. afterward I put my Turbo OBDII app on, all seems fine except that the TPS stays constant around 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I agree to the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know since I be close to you? No, I guess that is it.

Might as well as be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a fast irregularity locate if you unplug the meter and manage the engine without it. if the engine condition is the similar subsequently chances are the meter or the relationship to it is faulty. Its plus worth cleaning the MAF sensor wires, as they can get coated subsequently dirt greater than times which after that offsets the reading. Use some contact cleaner or brake cleaner to spray can onto the wires to separate the dirt on no account adjoin the wires considering everything as they are very fragile

I don't have any check engine lights unless I unplug the MAF sensor. past the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is then an intermittent popping sealed coming at idle.
