NISSAN Exalta SLA 2000 - Palyado Makina Problem

[ismori84]

Hi Guys,

My beloved Nissan Exalta SLA 2000 Model got submerged sa baha (lagpas bubong) in our basement parking after bagyong ondoy. Pinasok ko na siya sa Auto Shop. Ginawa na lahat ng necessary cleaning and draining ng mga fluids for a submerged car. Nagstart na siya kaso palyado pa ang makina. Pinacheck na din namin ang computer box and everything is normal. Malakas ang electricity and fuel injection is okay. Pinalitan na din ignition coil, maganda na flow ng electricity sa spark plugs (new spark plugs din). Wala ng problema sa starting ng engine (single click na), PERO once you put/press the gas or i-gas siya, palyado ang makina. Para siyang nagchochoke or nahihirapan. Ano kaya ang pwedeng maging problem ng engine? Need help mga Pare. Nag-aalala talaga ako sa auto ko. Wala na kaming maisip na solution.

Maraming salamat! Please I need you help.

Na pa check mo ba kung tama ang engine timing .

Napacheck na ang timing. Pero ayun pa din, palyado pa rin ang andar..

You can have it brought to Speedlab and let them use their diagnostic computer check your car's ECU for error codes, etc.

I assume ECU and computer box are the same. We already had it checked and scanned. Everything is normal according to the readings. Hopefully, the airflow system sensor is the problem. We have no other ideas for the cause of the engine problem.

Thank you again for the help.

Parang naka-limp mode nga yung takbo, pero pag limp mode the check engine
light sa dash board ay nakailaw.

Wala ka bang detailed check-list ng mga ginawa sa auto shop.

Nagalaw ba yung timing during the process, some mechanics are too lazy to remove all the timing cover for proper timing belt reinstallation.

Sa casa mo ba pinagawa, ano yung capability ng OBD nila.

Di naman ba palyado yung idle, pag-on ng aircon do the spark advance mechanism work.

Kung malapit yung Spedlab sa inyo di kaya mas ok na kumuha ka ng 2nd opinion.

Are you sure the engine ECU is fine? It might be running on "limp" mode. It would explain the lack of power.

Or the air flow sensor is busted/defective. Assuming the engine can idle using default settings but cannot run at higher revs due to improper signals from the air flow sensor.

We tried to replace the airflow system with a surplus one. But still, same thing happened. We are trying to find another replacement airflow sensor again, it might be the surplus one is also busted. About the "limp" mode thing, how will you find out if it's in the said mode? do you have any other advice for the cause of the problem?

Thank you so much for your help.
