I don't know if the 2001 v10 evan has a knock sensor
Yes...the V10 2v does have a knock sensor and it is located under the intake manifold. The "official" procedure is to remove the intake manifold, but I have read here on FTE that some folks were able to remove it without taking the intake manifold off.
IMO...what really needs to be done is check the fuel pressure...while idle and under load. That could lead you in a direction...for getting this corrected.
Did you use Motorcraft spark plugs when you did the maintenance?
I agreee with the o2 sensors and the fuel pressure directions. If your dealer doesn't know where to go if there are no codes, I'd find another dealer. The Ford Technical website has procedures for troubleshooting problems like this without codes! They don't want to bother with doing real mechanic work.
Check your intake system for leaks too. I wouldn't be suprised if you have a leak somwhere after your MAF sensor. It won't always throw a code, especially if it only leaks under heavy load.
Check out your intake hoses from the MAF to the intake first. I'll be you'll find a leak.
Mine pinged and idled rough and it turned out to be a hole in the pcv vacuum line. I replaced the hose and unplugged the battery for 20 minutes. Problem gone.

The Ford tech website is only for Ford techs. My fleet shop has access to it through our Ford contract. Saves us $$ doing the repairs ourselves. I'm still waiting on my Ford scanners to arrive.
just wanted to know how to get rid of the P1000 code and what the rules are for passing smog if this code is present and will not go away. Krewat posted some interesting info. about the 8500lbs and over trucks having OBD-1 instead of OBD-II. I am taking my truck back to the smog tech tomorrow morning and basically told them I need to get it to pass smog. cuz my tags are almost 2 months overdue The measured levels are not even noticable, so I don't know how they can fail it for a none emmissions code. I think need to read the EPA/CARB rules alittle more about that code.
I have an 02 SD 4X4 V-10 that pings also and it only has 40K miles on it. I too replaced the fuel filter and had the Ford Dealership flush the fuel system miles ago. The manual says use regular/Low octane fuel but lately it's been pinging while climbing hills. It never used to. I use Chevron gas, maybe I should try another fuel?

You could always try a different fuel, but have you ever cleaned the MAF sensor? That is where I would start...plus it is always a good idea to clean it once a year...or in my case living in the dusty Southwest...2 times a year.
I am beginning to beleive this is a fuel problem. The fuel is not what it is supposed to be. I have not yet heard of anyone who has fixed the problem besides upping the octane.

My '01 pings too, with only 30,000 miles (36k now). Going from 87 to 89 octane did away with 90% of the pinging, but I just noticed with the last tank of 89 it is starting to ping more.
