Hyundai Grand Starex – Black Smoke, Rattling sound and Loss of Power

Have you ever encountered a tail pipe black smoke, Engine knock like a rattling ratchet followed by a sudden loss power?

I was driving from Calatagan via the Nasugbu, Tagaytay road at high speed when all of a sudden, a sound like a rattling noise of a ratchet, black smoke and sudden loss of power was encountered.
I immediately parked on the road side and checked what went wrong. I opened the hood, It looks everything was just fine and in normal condition. Temperature was 86 Degrees C ( HUD* Information ). Cooling water level was good, No any sign of leaks.

I tried to restart the engine, It started, but the black smoke and rattling sound still there! I was sure that something’s really wasn’t right!

Petron value card was reliable. They managed to arrange the towing service after valid verification of my Petron Value Card.

After approximately 30 minutes that I didn’t do anything on the Car 🚗, and while waiting for the towing service from Silang, Cavite, I started the Car one more try!

With luck and good fortune, The car started normally! As if there was nothing happened!

I manage to reached Twin Lakes at 1500 RPM as an observatory acts.

As soon as I arrived Twin Lakes, I called m back again the Petron hotline and canceled the incoming towage service. They confirmed without any additional information needed. They even called back and advised that if I need any additional help, They should be inform soonest to arrange another service!

Thanks to Petron customer service provider. The card has a real value honestly. #Petronvaluecard

We arrive at Marikina without any reoccurrence of black smoke, rattling sound and loss of power!

As a peace of mind, I still need to check my injectors o rings. It might suck or insufficient air that cause the loss of power at high speed. Insufficient air and fuel ratio equals insufficient combustion. Air in the fuel line causes knocks. At high speed, It make sense but further test should be very crucial.

Black Smoke, Rattling sound and loss of power is back to normal.

•Following the recent issue that I just encountered a few days ago. Here is the latest results of my Car injectors after we did some slight adjustment at awons corps auto supply.

We found out that there is loose socket connection on number 4 injector.When vibration occurs at high speed, It cause number 4 injector to stop due to intermittent disconnection. We discovered also a slight  loose nuts tightness on fuel high pressure lines allowing the system to suck air and mixed with the fuel. This causes fuel knocks like a rattling sounds.

Thankfully, The unit is back in normal operating condition even at 5000 RPM in park mode. Revolution is very smooth up to the red line.
