Hi

I've got a  (minor) problem.

When I accelerate I can hear a whistling/wheezing noise.

It doesn't happen when:

- The car is stationary and the engine is idling.
- The car is in neutral
- The car is moving at a constant speed
- The car is decelerating
- The clutch pedal is depressed

The whistling/wheezing occurs only when the accelerator is depressed,
ie the car is moving, gears are engaged, and increasing speed.

The car is a 1994 Ford Escort 1.6 LX fuel injection with Zetec

Any ideas?

A hole/split in a rubber hose in the intake system ?

Stuart

Is that easy to diagnose?

Obviously as it only happens when I accelerate I'm restricted to
testing when stationary.

Yes - I'd got to the same answer before I'd finished your post and read
Stuarts. The engine is old enough for a rubber hose to have perished or
cracked making this noise.

Stuff a rag into the air intake and listen. The restriction there will
encourage the leak to develop. DONT rev the engine or the rag will get
sucked into the intake hose and might not make it as far as the air filter
before jamming.

Thanks - I'll try that tomorrow (today?!) and report back.....

Brings back memories from the 60s of a co-worker's old Ford Anglia with 
windscreen wipers driven by a suction pipe from the air intake.
The engine kept cutting out on tick-over, and a lunchtime group from the 
office diagnosed a perished wiper hose.
