What causes my car to lose power and misfires at the speed of

110 mph, and backfires when slowed down??

 

hitting your speed limiter?

 

No Ellik

not the speed limiter ... sometimes that comes with hi- RPM ....

 

so,........

 

v6 camaro's have a rev-limiter from the factory. It normally cuts the car off at about 110 mph. i've hit mine many times. its nothing to worry about. the only way to get around that fact is to unplug the sensor on the transmission, only problem is that you can't see what speed ur running. l8tr
