today when i turned on my 94 camaro, my cars rpm in park and neutral has been at 2500 rpm instead of in the usual 1000 rpm area. does anyone know why this is? when i put the car into drive it goes on its own. when i brake it feels like the car is fighting against me to keep going.

 

I had a truck that did pretty much the same thing. I dont know if it would be for the same reason but in my truck the throttle was sticking.

 

yeah, i'd give the throttle body, and ALL its sensors a clean... then reset the pcm and try from there

 

it's got to be one of the sensors on the trottle body I believe it's the TPS (Trottle Position Sensor)

 

This is very weird but I have the exact same problem with my 1994 3.4l in park the RPM's are at 2500 I put it in drive and it goes back to 1000 on its own!

 

i'd put money on it being the IAC - idle air control, sensor... kinda makes sense that that'd be the problem

 

I just posted like an hour ago about high rpm's and I just solved it!!!!!!!!!!!!!!!
I cleaned the plugs with an air compressor and messed with them while the car was running (in park of course) just turn on your car and plug and unplug the two sensors until the RPM's go down it worked on mine! hope it will work on yours!

 

could be a vacuum leak somewhere, too. i'd check for that as one of the first things.
