" Senior Editor Mike Allen answers readers&amp;#039; car questions. Q: I own a 2000 Dodge Durango with 87,000 miles on it. The car has been making this squeeking like noise when i hit a bump, now even when I drive. Someone told me its the &amp;quot;bushing&amp;quot; not quite sure how its spelled, but can that damage how the car drives? I haven&amp;#039;t had a chance to take it to a mechanic. MELINDA FLEURY A: There&amp;#039;s a bushing just about everywhere the suspension attaches to the frame--probably more than a dozen. This can probably be cured with a good shot of silicone spray, but I&amp;#039;d have a mechanic check the suspension in case one of your bushings is starting to disintegrate. Q: My daughter has a 2000 Mazda Protege. For the second time in 77,000 miles the Check Engine light has come on. The diagnosis by the dealer both times was that Decarbonization was needed at a cost of over $300. What can be done to prevent carbon built up? One of the service advisers recommended BG Products 44K. Does this help? At $20 per can, it won&amp;#039;t take long to reach $300. TED WOODS A: Chevron&amp;#039;s Techron product is pretty good, and a lot less then $20. Q: I have had both American and foreign cars and from experience I like Toyota and Subaru best as I keep them for 8-10 years. I am going to buy the Toyota Matrix AWD in July but also am considering the Pontiac Vibe which is suppose to be built by Toyota for GM. My question is what is different about the two? My employer has a benefit package that gives a $3000 discount on GM cars. So that definitely makes me lean towards the Pontiac. Anything I should be aware of on the GM? Did they cheapen up parts on it anywhere? Thanks. ED NADEAU, PEMBROKE, MEA: They come down the same production line, so there really isn&amp;#039;t any difference in quality. Of course you have to deal with the Pontiac dealer...Still $3K is a lot of money. Q: Recently, I read an article in which the plastic trim/molding along the exterior of a vehicle was discoloring, and you had suggested an aerosol spray paint made for plastics to redo the fading paint. In the article, you did not specify or recommend any particular brand--just that it must be for plastics. Would you be able to please recommend a brand for me? Or, at least tell me what to look for when shopping. The closest I could come to something made for plastics is a &amp;quot;bumper coating&amp;quot; spray to rejuvinate aged bumpers. Thank you for your time and help. CHARLES A: Dupli-Color  "^^<http://www.w3.org/2001/XMLSchema#string>
