The assembly was $45. Thank you but I used an $8 water line hose with a 90. If I have to change it every year I will break even in 5 1/2 years.
BTW - I have been having erratic idle, stallling at first start-up when under 70 degrees overnight. It always smoothed out after 1 mintue or two, but it began stalling in the driveway and really getting bad when the CEL came on and 171/174 appeared. Past year I have only put 6,000 miles on it, but the mileage has been HORRIBLE - 10 mpg at best around town. exhaust has been smelly rich for a long time. I am only on my first tank of gas, but it appears to have booseed the mileage significantly. I'll track it for a while and see.
It must have been leaking for a long time, but not triggering the CEL.
Get in there and change it out!
