I have a 2007 Acura TL. Car has had on/off issues with the throttle sensor. Manifests by the car idle but won't rev up or move. Used to be that when you switch off and restart the car, it begins to work again.

Lately, the problem has become really bad. Once it happens even if you restart the car 20 times it won't work now. Also the car goes off in the middle of the road when you slow down. Also goes off when you make hard turns. Very dangerous as it has happened on expressways and busy roads.

The electrician I engaged says the entire wiring system is bad and needs to be replaced along with the brain box. Cost is estimated at 120k.

Want to find out if that is the likely problem. And if it is, is this a fair price?

I had the car scanned and it threw up the following errors: P0506, P2122, P2176.

P0506- idle air control system Rpm lower than expected.
Faulty air control solenoid, circuit problem

P2122- Acura Accelerator Pedal Position Sensor 'A' Throttle Position Sensor 'D ...

Accelerator pedal could be bad which is not most likely

Throttle actuator, circuit problem

P2176-Throttle Actuator Control System Idle Position Not Learned.

Where is the location of your car and what test has been done to proof beyond reasonable doubt that the wiring and ecu is bad.

Car is in abuja. I've changed the throttle sensor twice before. The mechanic's word is the only proof I've got.
