Hey everybody...i got a RPM problems with my car..1st-after the car warms up, the rpm's drop to about 500rpm's and the whole car vibrates like it wants to stall........2nd- when driving the car, after the tach climbs past 2500rpms, the entire car vibrates...has anybody had any of these problems? What is needed to correct these problems?

Thanks for the help

Start by cleaning your throttle plate. (K&N flows great but doesnt filter worth crap.)That should take care of the low idle.
