Please i need Urgent assistance....I have a 2002 Toyota Highlander and its giving me headaches. When the car is Park Mode and the Engine is ON, it sounds so sweet and calm. But once its engaged on Drive mode, and you try to move the car it will make a pop pop sound and jerk on first movement from the air filter box. Once it succeeds in moving, it will accelerate well until you stop and same problem will surface again.

The plugs are firing well.

Please how can i get out of this problem.

you should scan and take vehicle for proper diagnosis. But from past experience with your vehicle, you are dealing with an airflowmeter or fuel pressure issue. It's also possible your timing is retarded by a few degrees

The mechanic replaced the Airflowmeter and a complete Fuel Pump cause he also suggested same thing. But the problem is still there. Am just confused.

Thank you so much
I scanned with Torque and i got fault code P0758 - Generic (Type: Powertrain - Transmission -ISO/SAE Controlled) (Description: Shift Solenoid "B" Electrical), P0758 - GM (Type: Powertrain-Transmission -ISO/SAE Controlled) (Description: Transmission 2-3 Shift Solenoid Electrical Fault) (Cause: P0560) and P1155 - Toyota (Type Powertrain - Manufacturer Controlled DTC - Manufacturer Controlled) (Description Air fuel sensor) California - RH front - heater circuit malfunction (Cause: Wiring, air fuel ratio sensor, ECM)

I am not a technician and my Mechanic is good at what he does but this one is kinda much for him to handle. He is currently trying to check the plug coils and nozzle, i called him and advised him to work on the timing as you advised, he did and said its ok. And surprisingly the fuel pump is running continuously even when the ignition is off, unless when the battery head is off.

it's a transmission related problem.
