IT IS DOING WHAT ITS SUPPOSED TO DO. THE REV LIMITER IS TO KEEP YOU FROM HAVING HIGH RPM WITH NO LOAD ON ENGINE

Have 1999 cavilleir does it have a rpm protecter


Yes, the PCM for your vehicle's engine has a rev/speed limit seeting programmed into it. Most stock, non high performance/police package vehicles usually won't go above a top speed of 97MPH. if you were to rev your engine while it was in park or neutral, once the engine reaches the cut out rpm limit preset in the PCM, it will cause the engine to cut back, then it will rev up until it hits the preset limit, then cut back, and it keep repeating that pattern. It may sound as though you have a high rev ignition failure that sounds like waaa, waaa, waaa, waaa, but that indicates the PCM is doing its job.

Idle high then cut off


Most likely need the idle readjusted. Your vehicle has a high idle rev limiter that will shut down the motor to keep it from getting damaged. Make sure your accelerator line isn't being pulled on. This will pull on the gas pedal just like having a foot on it and will rev the motor as well.

Cuts out on high revs 240 chain saw


Many saws made today are using electronics for engine control. If the engine rpm's starts to rev to high, the electronics in the coil will start to 'cut out' some of the spark. This is normal in this senerio.

But, now the real problem causing the senerio;

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
5) replace gaskets/diaphragms
b) use a spray carb cleaner to clean jets, holes, and body of carb

Engine cuts out


Maybe when you went into the ditch you partially pinched your fuel line so now your not getting enough fuel to the motor?Crawl up under your car and see if you can see any damage to the fuel lines, or anything else...filter etc.
