because someone probably turned the engine on
Check your EGR valve..if its the XUD9TE engine then it is a green clip to the left of the battery
When it makes that noise it is either because your reving it to high or just because your engine is goin
yes. ECM has protection on over-reving the engine...
park it in the garage until you work out what problem you have
rev limiter, engine will sputter when it hits this limit to keep engine from over reving
Thousands of people have been really satisfied with the AEM Cold Air Intakes and I think it would be the perfect choice for your high reving GSR engine as it flows very very high. Cheers, GPI Performance
throttle plate stuck, accelerator cable binding, vacuum leak, tps malfunctioning.
its called a rev limiter. It keeps the engine from over reving and breaking.
Can be a multitude of things. First see if its from inside the engine bay and occurs while in neutral reving the engine. From there check your headlight assembly.
If by tick over you mean when should you shift, then it depends on how much torque your engine is producing. You will discover as you drive that shifting between 5000 and 6000 rpm assures maximum torque from the engine. Mazda does recommend reving the engine near redline (approx. 8500 rpm) several times a week to eliminate possible carbon buildup. I personally love the feeling of shifting at approximately 6500 rpm to keep it in a lively range. Remember rotaries love to rev, and reving it high (above 7000 rpm) is actually good for the overall health of the engine.
It is not bad at all.
