1994 Infiniti Q45 4.5L from North America
Fuel pump, water pump.
The car is great, but the engine started whining at about 90k. The mechanic I use can't figure it out. It seems to come from near the belts. Just a steady whine that increases and decreases with RPM's. Any help would be appreciated at kevin.anglim@UBSpainewebber.com
Would you buy another car from this manufacturer? Don't Know

Have the timing chains checked. This is an interference engine. When the chain goes, so does the engine. It's a common Q45 problem.

I have a '90 that developed this sound 4 months ago. Found an Infiniti specialty shop in Atlanta that pointed me to the set of pulleys on the front of the engine. $100 and sound gone!

I also have a question on a 1994 Infiniti Q45. I just bought it about a week ago, and the guy said it was cutting off on him. After I drove it for about a week, it started cutting off on me. When you go to stop it will just cut off. Also when I was driving today, it would try and stop going as I went down the road. It is like it is not getting enough gas or something.
I took it to a mechanic and he put the computer to it, and said that the mass air flow sensor was showing up and that the knock sensor was also showing up. This car has two knock sensors on it at $190.00 each. So by the time he put on the 2 knock sensors, the bill came to $600.00 and it still jerks. I am hoping someone can tell me what might be wrong with it? I don't have any more money to throw away!!

Mine was making a whining sound too. It turned out to be the power steering pump. It had a leaky line, and when it's running low, it whines.
