I did the search of the code. Found out alot of use info. My issue is taking it to the dealer
SES p0089 repeatedly for about 4 days...

I've got a 2001 c/c 4x4 dmax. with the Edge w/ ***. 71,000mi.
Suncoast stage 5 trans
The muffler was removed from the exhaust, dynomax 4in. silencer installed.

I'm in Orange County Ca. Does anybody recommend a dealer in the area.
Do i need to remove the Edge???? probe has the stay in manifold..
Would like to know what is covered under the 100k warranty. From what I've read it should be except for deductible. Do you think there going to try and void warranty because of edge. What should i expect to pay ?
When i'm at the dealer should i ask for the reflash of the ecm. Never had it done. And have them look at balance rate of injectors.
