I have a 93 Areostar with the 4 liter v6. I just had the throtlle body cleanned and the idle adjusted. It ran great now it has developed a very rough idle and is very rough while driving. Could it be spark plugs? How easy are they to change? I looked but can only seem to see them on the driver side of the engine. Is there an easier way to get to them? Also how do I get the interior engine cover off, I found 3 latches and I still can not seem to get it off. Any ideas?
Your rough idle problem is very common and has been addressed just recently in this forum. Look down the list of threads and you will find a discussion of the idle problem as well as how to rmove the interior engine cover.
If you want additional details, you can also do a search using the search button at the top of the screen, the one between 'f.a.q.' and 'home', not the one on the right hand column. You need a minimim of four letters per search word or else the search feature will not work correctly.
Try the suggestions in those threads and if you still have problems then post back. Good luck!
