I just put my 17"s back on and now I have a rattle on decel around 2300-3500 rpm. Goes away when I put slight pressure on the gas peddal. Sound like a deep rattle not tinie like an exhaust rattle. It is coming from the front. I have Cusco mounts and the rattle was not there when I was running my snow tires. My 17"s have Falken RT615 235/40/17 on them. Any ideas??

put the other tires back on

if it goes away my guess is extra road noise from the tires


but if its a specific RPM and not MPH that makes me question what i said alot

Ya its only at a specific RPM, I also found out I hae 2 injectors that gave up the ghost. It might be that on decel I am getting a strage vibration from the engine causing the rattle. As soon as I get the injectors taken care of we sahll see. Thanks for the post.

could be the turbo headshiled rattling against your downpipe, aftermarket downpipes usually dont have a place for the last bolt, take off the heatshiled and drive around and see if it helps, if thats the problem, then cut off the piece of the heatshield that doesnt bolt up i had the same problem

Sorry I havent posted for a bit. i found out I fried an exhaust valve on #1 cylinder. I have to pull the engine anyhow so i hope to kill the rattle at the same time. I am thinking that it may be due to the dead cylinder but I am not sure yet.
