SOURCE: Cold Start Idle Issue

Problem might be the air control valve, it's located at the right side rear of intake manifold and has a hose going to the air intake duct from the air cleaner, as a test you might try pinching off that hose when the idle is a problem.

1999 Yukon Start Issue - I have replaced the octopuse, battery, fuel filter, fuel pump, still having problems starting in cold weather, sometimes after a heavy rain.

Any suggestions?

Thanks

first check cylinder 1 , spark plug, ht leads, coil,

then clean the trottle body with carb cleaner

if that does not work replace the throttle body, comes complete, and do a basic setting on it with diagnostic machine

I had the exact problem with my wifes 99 Cabrio - parked for 9 months. Ended up having to have the shop reprogram the ECU - it then worked fine.
