Today i was driving around and i pulled her out of the drive way and my car felt VERY jumpy, and my RPM's were skyrocketing when i hit the gas. i have no idea why this is happening? any ideas.

 

check your floor mats ... if they bunched u under the pedals it'll do that

 

no.. they arent.. i thought about that as well as if mabey teh mats were making the pedals stuck but there was no interference with the pedal at all
My brother has had this issue with his 1995 pontiac firebird in the past but he just took it to the shop and they fixed it for him... he said he forgot what the prob. was because it was a while ago.. so any more ideas on what would cause this

 

oh and also when i sit at a stop sign, i will be sitting there and teh rpm's will drop down to below 1,000 and if i wait about 5 seconds the rpms will Jump and the car will jerk like it wants to move but i assure u that the floor mats are not in the way

 

my car wuz doin the same thing. i would sit at a light and they would drop to 400rpms. what i did is i replaced the spark plugs and spark plug wires and it fixed the problem. but it could be something else because mine did not shoot up my rpms. i would change them anyway and see if this resolves your problem.

 

try cleaning out you throttle body if that does not fix it ti is you iac sensor

 

Yes.. thank u 99 avenger, the sensor did the trickk.. i took it to a shop and they fixed it in no time.. thanks to all

 

no prob ask any thing i work for dodge

 

im having the same problem for example i was sitting at a stop sign and as i pressed the gas the rpms went up but the car didnt move until the rpms got to around 3000 then itjerked a lil bit and took off....question is how much would it cost to take to a shop and get looked at?

 

That sounds like a tranny issue. Does this only happen when the car has warmed up or has been driven around for awhile?
