msd
ECU P72 and the car was never tuned !

 

clean your IACV and delete your FICV.
tune doesnt have anything to do with it.

 

1) If you cover the top of the throttle body of the idling engine, does the engine die?

2) The starter may be bad.

 

how do i delete my FICV?

 

Never tried the first step will do ,

and starter is bad i would need to replace asap!

 

its under the TB.
loop the coolant lines from your IACV ot the intake mani.
its daisy chained.
from the thermo tube to..
iacv to
ficv to
intake mani.

jus by pass it and make a block off plate for it.
you dont even need it. its too warm up the car faster.
but not everyone lives in a cave or in canada.
but it makes a nice TB heater for the summer...
