I just recently tuned up and serviced the transmission on my dads pickup. Everything was working fine on the hour drive back home and i noticed the wiper fluid motor wasnt working so i checked it out re-seated the connector and got it workin but i ended up running the battery down. So i charged it up and ever since then it has started just fine and idles but soon as i start goin down the road and brake to a stop with the vehicle in drive it stalls but if i put it in neutral before i stop it continues to run, and when i put it in drive or reverse from idle it bogs down for a second but then regains rpms. i dont know if its a voltage problem or maybe a fuel problem... can u help me out

Have you checked for vacuum leaks? Has the check engine light come on?

Let me know.
