Pedal sensor? Light throttle on freeway
Hey guys I've noticed when going down the freeway at a point that is usually downhill and just barely on the throttle I will feel the car periodically slow like it's being hit with a gust of wind.. or like I'm letting off the throttle maybe.. yet if I let off completely and coast down it seems to be smooth.. the transmission is new with a 2000 stall. I have been having a very slight idle variation so small you can't detect it on the tach but you can hear the drone change at idle so I'm wondering if that could be it, or the pedal.. I thought I changed the TPS but thinking back I changed the crank and cam sensors I don't think I did the TPS. Does anyone have any ideas? Plugs and wires are brand new too. Just spent $700 on brand new factory injectors haven't installed them yet though.
