Can I clean my IAC valve and vacuum switching valve with throttle body cleaner while car is running? Will this damage the engine? My iac is in a bad location and I don't want to remove it until I get a new gasket. Can I just do a quick cleaning by spraying it into the iac while engine is running? And for the VSV... throttle body cleaner? Or soak in seafoam? Anything else that works better?
