here's a tuffy
so i was driving my mom's 03 trailblazer and i was doing about 50 and i was about to go down a hill so i put it in neutral hoping that the rpms would drop, they didnt, they stayed at the same place the hole time even when i slowed down to about 40 they stayed the same. once i put it back into drive the rpms went back down to normal. weird huh. is this supposed to happen or what??? any info would be great. thanks

Re: here's a tuffy
The engine speed is controlled by the computer, using inputs from the TPS, Crank sensor and a few other parameters.
What you experianced was a normal operating condition.

Re: here's a tuffy
ok, so you're saying that the sensor for the rpms is not connected to the motor at all, weird, oh well. thanks for the answer though.
