[taka21]

ok so when i start my car cold it idles up around 1500 like it should then once it warms up it drops down to like450 or just stalls out
when i start it warm it wont hold an idle untill i hold it there manually then it catches up but will idle like i said at 450 and want to stall out
any ideas
i have already cleaned out the iacv and the tb

Replace the capacitors in the ECU. Lazy and rough shifting of the auto can also be associated with this as can a lack of OD and lock up

its a manual conversion so no auto trans at all

Puter don't know that. Reset it. Battery off turn something on and a brisk drive in the morning.
