any direction on code p2172

Question

replaced ecm, throtle accuator, now have code 2172

Answer 1

the main problems for the code on this year will be caused by the throttlebody, valve springs or you could have a fail'ed MAP sensor

 

also check for intake leaks. spray brake cleaner near the intake manifold and intake, and see if there is a change in idle. Dont spray brake cleaner on hose's and wires.
