Plenum Issue??? AIR system issue ???
I have developed a slightly rough idle on my 02 Deville. I don't have any codes other than the p0410 which I am about to get fixed.
The SES light is on because of the p0410 code obviously, but I've noticed that when I do a WOT or drive uphill, the light flashes and there is a very slight hesitation. Could this be plenum related or would the p0410 cause this?
I used some Techron the other day and I noticed some improvement. Good stuff...

Hey all you "looky loo's". I've been helped so much from this website. Cleared my P0410 code with a little effort and a lot of info from Sub 409.
So if that's your experience, then donate to the cause. These file servers don't run on love. Just put in some cash and pay it forward for the next guy..
