Engine reving

so i have 99 silhouette im finding that when im at a full stop and press the gas peddle that the engine seems to be reving higher and the car isnt moving as fast as the engine is reving...also the abs light keeps coming on i put brake fluid in it went away for a bit and came back... please help

Check the transmission fluid level. You may be running low. The abs is a different problem and may be a bad sensor or wiring. On should not cause the other.
