Check engine light in 01 Grand Caravan ES
Keep getting check engine light on 01 Grand Caravan ES 3.8 when i cycle the key 3 times i get codes 1684, 0442, and 0455 can someone diagnose this i was told that one of the codes is a small vapor leak i replaced the fuel cap and reset the light and it came back on 30 miles later. Im also getting a annoying loose rattle over bumps i changed the struts but still have the problem any input would be appreciated. tw_1717@yahoo.com.

Many, many possibilities. Use the search function and you'll get lots of hits.
To summarize:
1. Small hose behind air cleaner
2. Any of the hoses around the evap cannister underneath the middle seats.
3. Fuel filler pipe
4. Leak detection pump
And probably more that I can't think of at the moment. You can do an inspection and you might get lucky and find it but if you don't find the problem, a decent shop will have a smoke machine that will quickly find the problem.
