im sure you guys know by now I have an 84 cutlass with a Chevy 350. It's a fuel injected throttle body and its stock. I have a weird one today. So it's hard to explain so ask questions if you need more info. I know it's hard to know exactly over the Internet but I just need opinions. When first started, if I go maybe about 3,000 rpm or around that (Not sure with no tac) but the engine surges and acts as if it will stall. If I keep the pedal constant after a couple seconds it starts to kick in and accelerate normally. And even sometimes when it's warmed up it also does this. I've been thinking its tps but I just don't know how to figure it out or what to do
