YJ Stalls out HELP!

i just added a rock it intake, and a new exhaust manifold, and today i was driving to work, and after i try to come a complete stop, i see the RPMS just drop right to 0 and the jeep stalls out... anyone have any ideas? could it be possible that the intake is sucking in too much air? Keeping in mind this is a 95 wrangler with TBI... one thing i have to look into is that one of the breather hoses from the original intake is not connected because i added the new intake and there is not a port for it ( it dumps into the emission canister )

I also put on a new belt when I did the exhaust manifold and I had the power steering pump off. Could it be the timing ? Maybe I have to adjust the belt

Yup. Had no issues other than the cracked exhaust manifold. The only other things I changed were the serpentine belt and the intake

Mine was doing that and I have a 93 and it was the alternator. Watch the voltage gauge when it dies. It'll drop if its doing what I think it is.

That was it!! The throttle position sensor was bad. Now it stays at a steady idle.!!!!!! Thanks man! And to everyone else who helped out.
