Well I have cleaned the throtle body valve like I should, but the idle on this truck jumps all over the place. At a stop it will sit at 1k for abit then drop to about 700 RPM..today it stayed at 1K with the AC on..is this normal?..cause it's kind of scary not having the engine help with braking.. btw this is on a 99 f250 5.4 gas ,

 

If it's sticky, try adhesive remover.

 

haha that was funy...lets try this again..step on the gas, idle stays high, when I step on the brake..the idle stays high, for a second, then drops from 1k to 500. In a heart beat ..there does that explain it a bit..thanks,
