Called dealer and they want $151.14 for the part. Did search on ebay, could'nt find. Any suggestions or is dealer the only source? Also, would this cause engine to idle at around 1k at startup, produce a very smelly exhaust and result in reduced gas milage? Thanks for the help.

 

I'm having the same problem. Very rarely do they actually go bad, they just need to be cleaned out, or the solenoid valve needs to be replaced. Also, it's isn't supposed to hurt gas mileage.
