rebuild engine shuts down

[dany5.0]

Please help me with problem that I have with my mustang, I rebuild my engine with e303 cam. The car idle good when is in park , the car runs good but when I'm coming on a stop , the engine shuts down and wont idle, I already put a new idle speed control, tps I dont know what to look now, please any suggestion.

not sure about autos, but on sticks, the VSS keeps the rolling idle higher to accomodate extra load (PS, electrical load, etc).

no other ideas jump out. good luck.

Hmm...well what exactly is everything you did for the "rebuild"...what things did you mess with...?

A temporary fix to your problem is where you can adjust the little idle screw to keep the revs up a bit higher...until you find the real reason...if you need to drive the car as a daily driver...

VSS = vehicle speed sensor

ok, gotcha (when you referred to having the car in park, i assumed you had an auto).

5sp recommended what i would have said too.

are you getting any codes?

good luck.

I rebuild the engine and I did AOD TO T5 swap that's all I did also before I rebuild my engine i converted my speed density into mass air I dont know if that could cause the problem
