Good day tsikoteers!

Recently had my 03 Xtrail 250x diagnosed from Nissan Westgate Alabang. The problem was whenever I start the vehicle it does not idle properly and the engine looses gas and dies. Also I have also noticed a considerable loss in power in acceleration.

Nissan Westgate told me that the problem was the idling throttle and it would cost me around 36k to change the part.

Computer Diagnostic result: IDLE AIR VOL LEARN INCOMPLETE
ENG SPEED 450RPM

If anybody can direct me to a reputable but cheaper motor shop for nissan parts I would greatly appreciate it. Thanks

Marlon
