Hey guys, I own a '02 Ford Taurus... yes yes I know, huge piece of shit. Anyways, one of the pulleys for the belt on the engine is starting to squeak. The higher the rev's go, the louder the noise gets. The noise just started and the car drives fine otherwise, so I'm pretty sure it's the pulley wheel that's the problem. The belt looks fine still. The car has about 95k on the clock. Anyone know approx. how much this will cost to fix? I want to know some numbers before I start calling around. I've only lived in Columbus, OH for a few months so I'll more then likely take it to a stealership to get it fixed. Could I be okay to just try to buy some WD40 or something similar and just spray the badboy down? Also the car was starting to go funky when in park, or in drive at low RPM's. The RPM's would dip and come back, there was enough deviation in the RPM's that you could feel it. It wasn't major, but you could feel it. I felt like it was something to do with the fuel pump or filter, so I dumped in some additives for the last two times I filled up my tank that claim it clears the fuel filter up. So far, this has totally gotten rid of the problem. And since it has, it leads me to believe it was the fuel filter. Is it safe to continue to use those additives like that? Should I have that changed? Anyone know the costs associated with that?
