Dave,
That should be enough. Have you changed your DV yet? I got my first CEL right before the National GTG last year. I changed my DV and it went away for a little while. I got chipped and it came back.
So the DV was responsible for the first one. Once I got chipped the point of failure was either the hoses, the MAF or something else. Once I got my A/F gauge, I could tell it was MAF related since my readings were all over the place.
I ended up getting a new one and that solved my problems. So here is the order I would follow to fix this, hopefully yourself:
1. Hoses, replace with 3.5 or 4mm vaccum hose.
2. DV replace with the 710N (yours will say the part# is xxxxxx710 with something other than N). If you take this off and you can easily push down the diaphragm, it's time to replace it.
3. If those three don't do it, and your air filter is clean, I would highly suspect the MAF. You can order one from Tim at Liberty for ~$158 instead of the $250 they charge at the dealer.
