About the only thing I can think of on the rattle is a broken gear tooth or a cap nut from and OHC mount has come loose or has come off and followed the cam chain down into the gearbox. I would be leery about riding it until the problem is found. The last thing you need is to be sliding on the concrete in traffic after the rattle gets in the wrong place and locks ou the gearbox at 60 mph.

Mazda tribute revs to 4200 misfires


Is it misfiring or is the high rev limiter kicking in? Mazda's are not high rev engines even with the ford engine in it! mine idles at 750 +/- and hits 2500 at 75 MPH if I punch it it will go to 3g but not much higher.

Good luck

Hi:
Does your cars check engine light come on or off at all? If you had a misfire, it would trip the check engine light. Often a misfire is caused by a bad ignition module, and not just one sparkplug, but the only way to see what your car is doing is to have it scanned to see if anything is stored in the memory. Often , auto parts stores will do this for free, and that way you might have a clue to what is going on under the hood!
