Sounds as if your catalytic converters are plugged up. It's not a cheap repair, if you do it right. You have to replace the 'H' pipe, which contains the converters. That pipe may set you back 5 or 6 hundred bucks!
An emergency fix (though not legal) is to remove the existing pipe and with a long steel rod, bust out the guts of the converters. You have to shake out the contents after you bust them up so it's necessary to have the pipe off the car.
If you want to test and make sure that this is the problem, you can disconect the pipes from the exhaust pipes coming down from the engine without removing them from the car. Start the engine and try to rev it up, without the converters connected. If it revs like a 'racecar', you have probably found your problem. Good luck! Dave

Rattleting noise seems to be the crankcase rear chain V6.Cyl 4.0 ford exp XLT 2002

Make sure the oil level is good. The hydraulic tensioners for the chain work with the engine's oil. If low it will make a rattling/knocking like noise.

Does a performance air filter make my car sound different? Just the air filter alone

If your engine is making a noise change the engine oil and filter with the manufacturers recommended weight (viscosity) oil first, if that does not make a difference engine repair work is needed .The better an engine can suck in clean air, the better it runs. So yes, cleaning the filter in your car can improve it and diagnostic out it .

My ford explorer (1997) won't start. It makes the


The little black box and different colored wires lead me to think this is a universal Oxygen Sensor (O2 Sensor) that has become detached. If you can find the other end--strip the wire and use a but connector with electrical tape--should solve the problem.
Without the O2 sensor the vehicle does not know how much gas and air to give to the engine (won't start).

Hope this helps--

When i accelerate in my 06 focus 1.8 i get a whooshing sound from the engine for a few seconds, i dont get it when i just rev it, any more ideas ?? Phil

This is just the throttle sucking air when the engine is under a load. When you rev the engine in park it wont make the noise as much or at all. Try driving it and slowly apply the gas and see if it happens.

Air sucking noise from below the intake manifold.

Look for a vacuum hose that isn't hooked up

might want to try charging the battery for a while on a battery charger.
usually when a vehicle does this, its because the alternator is trying to charge the battery more then normal causing the motor to rev higher.
