I need to thank everyone in the past as I used a combination of techniques to easily and quickly change the dirty air tube on my 2003 Deville. I of course removed the engine cover, radiator/front end cover, slipped the belt off the power steering pump with the help of a 10" 1/2 ext. on the belt tensioner (leaving it in place), removed the 1 bolt holding the power steering pump and was able to pull the pump towards the fender just enough that I could get a pair of slip joint pliers back to the spring clamp holding on the end of the 90 degree vacuum tube. I had to finesse the tube end a little counter-clockwise, which was easily accomplished because the majority of the dirty air tube was easily removed by gently pulling it and where the deteriorated 90 came apart - which left just a 1 1/2" piece with the clamp in the nipple. I could just get the pliers on the clamp enough to relieve enough pressure to spin the clamp counter-clockwise enough so I could then get a good solid grip on the clamp with the pliers and it came right off. I purchased a OEM Dirty Air tube for 14.60 at the dealer - and reversed the process. The whole process took about 30+- minutes since I had the new tube before I began,
I started the engine (cold) and it ran smooth, much smoother then I remember it for a long time.
I shut the car off for an hour and went to start it for a test drive - and it started dying, The car idles at low rpm now when warm and is hard to keep running with foot off the gas. I am not sure what the problem is now - other than the car was use to the progressively worse vacuum leak and now it has to get use to not having that extra air - and that is the current problem.
Can anyone confirm that the car will adjust to the new dirty air tube not leaking and smooth out soon - or provide a way so it will adjust sooner rather than later?
But again - just slipping off the belt and not moving it, removing the pump just enough to get to the tube - was just what was needed - thanks!!
