If you have white smoke coming out the exhaust,you may need to do a compression check on the engine,most likley the head is bad,or head gasket you replaced did not seat.

Thank you I appreciate your time to help I'll definitely check it out but is there anything else that you think it could be because other times she'll start and run with out smoke but then out of nowhere when she hits a low idle like at a stop light or we have to use the 2 foot method to keep her running or she'll just die and well that's why we are confused

This sounds exactly like a temp sensor gone totally bad. The ECM thinks it's 0 degrees out and dumps fuel to it.

I've also seen the AIC (Air Idle Control, right behind the TPS on the throttle body) cause similar issues.
