Hi Mr.Expert. It is hard to get a sample sound clip of the noise because it only happens when the car engine gets quite warm while running on high way and the tacho points at from 1900 to 2000 rpm. The sound is like when i use a compressed air to blow thru a small gap and vibrate a thin metal sheet in the gap. The sound is heard from the cabin on the left side of the engine bay,it is a very annoying sound. I have watched some youtube clips and heard something similar pulse solenoid faulty sound. But anyway i will try to record it. I brought the car to the local mechanics but they could not find it and asked me to drive the car back when it occur, i have not done that because i told them the problem and left the car a whole day for them to find down.
Hi Curtis. The engine fited in my car is petrol 4.5 lt.1fz-fe late model 1998. I've been told that there's no EGR valve in the engine,by toyota. My car is fitted a aftermarket POWER DYNE supercharger,the blower is quiet and the car runs on LPG too.
