super50 Posted August 4, 2007 Share Posted August 4, 2007 My '99LX has 94K miles on it. It is out of extended warranty now. I have noticed a loud metallic rattle coming from below the vehicle, only when I am accelerating, between 1500RPM to 2500RPM. Rattle stops when I take my foot off the accelerator. No rattle at higher RPMs. No relation to brake use. I can reproduce it by revving the motor while parked and seems to be coming from mid-vehicle or the rear. I cannot localize it further. The vehicle runs fine otherwise. Has anyone had similar issues? Does anybody have any ideas? Quote Link to comment Share on other sites More sharing options...
mehullica Posted August 4, 2007 Share Posted August 4, 2007 Common for the heat shields on the catalytic converter's to crack around the bolt holes causing a buzz/ rattle. There was a TSIB for this. L_EG001_00.pdf Quote Link to comment Share on other sites More sharing options...

Jim_Chow Posted August 8, 2007 Share Posted August 8, 2007 x2. The cat shields is a infamous problem on the 98-02's. The quick fix is to use a hose clamp. Quote Link to comment Share on other sites More sharing options...
