Grrrrr... Now she's stalling in reverse :(

New engine new suspension... Now this but ... I will never give up!!! Any ideas guys? I'm thinking iac, crank position sensor, vacuum leak... Or worst case scenario torque converter... Also noticed sporadic fluctuations of the rpms when stopped... Any thoughts?

Mine was doing that once... I forgot what's it's called but if you look at the throotle body and on it there's a round sensor that plugs into the right side... I changed that and mine ran fine afterwards.

Note: I changed the idle air control valve.

Your post seems like it's missing info, but mine was acting rough at idle and sometimes stalled.

Changed IAC today... Same problem... No codes... Seems like possible vacuum leak?
