Hey all! I've changed all of my vacuum lines on my 2.3 liter engine, but now, at a stop, the car shift abrubtly into Reverse or Drive and when accelerating, it won't go out/shift out of 1st gear on my Automatic? No the winter mode isn't engaged, it works when I push it, it just won't shift... I don't know what to think. All of the wiring is connected, I put the hoses on right, I'm just wondering does the shifting of the transmission have to do with the Air Injection Pump? Because from a type of sensor on the fire wall, it does down in front of the transmission to a little UFO looking plastic piece with the air injection hosed coming out of both the right and left sides, the vacuum line goes onto a little nipple on top. (ATTN: But before it goes to the plastic UFO, there's a little check valve with an orange side and a black side, the orange side says DIST on it, so I'm assuming it points up towards the distributor, and the black half says CARB, so I POINTED THAT DOWN TOWARDS THE INJECTION PUMP. I'm not sure what to do as I'll be stuck here and need to get back to school for classes tomorrow...
