Question about 1998 Ford Contour

1 Answer

Rattling post 2000 rpm in every gear

I own a 1999 ford contour sport. It has 140,000 miles on it. After a 400 mile trip, I started hearing a rattling sound coming from the engine area. It starts rattling (a sound like a helicopter or like when people imitate purring with their tongues) when I reach 2000 - 2500 rpm in every gear, under those 2000rpm, there is no abnormal sounds. The sound gets faster as the rpm goes up, in higher gears its difficult to hear over traffic sounds and such. When I take my foot off the gas, the sound goes away, even if still post-2000rpm range. What's going on?

Sounds like the timing belt tensioner. I have that problem. Rattles at low rpm, goes away as you acceralerate. Looking to have timing belts changed and tensioners replaced.

My check engine light is on & a diagnostic code check says it could be the catalytic converter (140,000 miles on vehicle), a vacuum leak, or O2 Sensor. What in your opion would be the most probable...


The catalytic converter being bad will definitely cause a drop in mileage and also a loss of power. Do you hear a rattling type sound when the vehicle is started cold or just when the ignition is shut off? Also if you bang on the converter with your hand, you may be able to hear the loose material rattle inside if it is bad. I think your Explorer has four catalytic converters also. What are the specific codes you received?

Are 2000 GTs with 100K + miles prone to need swaybar , shock, etc bushings? Mine started a rattling underneath and someone told me they were prone to wear out bushings. Is that so?


Sway bar and suspension bushings - Yes, Shock/struts yes if shocks/struts haven't been replaced already. Check stabilizer links before changing anything, Stab links wear out and are common to make rattling noises.

Does it seem to turn over quickly? If so i'd suspect the timing belt broke considering the rattling noise heard before it stopped.
