today i started my "85 manual 4+3, when i press the gas it stays revving where i took my foot off, not rpming up nor down and that's a problem when trying to shift gears. so i started putting my foot under the accelerator to pull up and "lo and behold" it eases up but upon reacceleration back to square one. notice it starts to ease up also when braking but only when car starts to slow down significantly. also noticed rpming up higher, before when doing 60 she rpmed at 1600 and today when this issue began at 60 shes around 2200 rpms, any ideas. thanx
