I press the gas on some days, Really loose, easy to kick into OD ( i have an automatic ). Other days i have to SLAM the pedal all the way to the floor to get it to even really respond to me. thought it might have been temperature, nope.. some days warmer and it responds better, some days it doesnt.. its wierd.. thought it was throttle cable, tightened it because it was really loose.. helped a small amount but its still happening... anybody have the same experience??? Thanks
