I have a 2002 Alfa Romeo 156, 1.8 liter engine. Regardless of the gear it’s in, there is a somewhat loud noise. This also occurs while in Neutral and the engine is “revved”. The noise sounds a bit like a chain being pulled from behind the car. IT also sounds a bit like - imagine this - a wing nut is loose on the air-filter housing and the washer is vibrating on the threaded post. The engine does not have an air-filter housing, but it does sound that way. Also, the noise is too loud to be a “loose nut and vibrating washer”. Any ideas? ---

This is a long shot. I had an intake gasket replaced on my 2000 Blazer. When I got it back it was making a similar noise under acceleration. I traced the noise to the accelerator pedal cable and back to the throttle body. One of the cable tie downs was not replaced after the repair work was down. I secured the cable with a tie wrap and no more noise. Ed B. ---

I think you may be better served asking your question on a European specific Automotive site. Fiat stopped importing Alfas to the USA back in 1995 with the 164 Sedans with V6 only and the old rear wheel drive Spiders. ---

AlfaDriver, I appreciate the advice. Tried that and got no where. Hoping someone might have had an idea. I do thank you though. ---

Ed B., Worth a try. At this point, anything is. Thanks! ---

If you haven’t asked yet, I would try this site. [http://alfaowner.com/Forum/](http://alfaowner.com/Forum/) Seems like the place to ask on newer Alfas. ---

Sounds like an exhaust heat shield rattle to me. Any muffler shop should be able to find and fix this in a minute. It’s also a common problem on many cars; not just ARs. ---

Sometimes you can locate these jingles by listening through a tube, like a vacuum hose. One end at your ear and scan slowly around the engine compartment with the other end until you hear it loudest. It could be something completely insignificant like a loose cable. ---

Have not heard of that site. I’ll give it a shot! Thanks again!! ---

Hmmm, now I never consider the muffler. I would have that since it dealt with RPMs, the thought of a tranny issue made more sense. Now thinking of it from the muffler, that make sense. Thanks!! ---

Outstanding suggestion. I’ll give it a whorl and see what happens. Outstanding suggestion. Thanks!!
