TOPIC: How well does a 2006 Ford F-150 respond to the Groove?

I have checked to be sure it is operating properly but I don't know what else to do I used to have it blocked on my old 1977 .I just don't know what to do with it on this newer model

What could I do to the erg system

I need to make a correction.i put the new gasket back on with the fins still on it but dremeled the part that was blocking the grove a little.with out the fins it seemed to drop my mpg. Any ideas about the erg valve.i pulled it off again and cleaned the little valve in side better.i just don't know if blocking it would help I've read it may hurt mileage to do that.

Miles,

I have seen mileage drop initially MANY MANY times, only to rebound in a few days to very respectable (over 25%) gains, so don't worry!

Probably just the ECU adapting. Wait a little while before determining there's a fault. It takes time for these things to work! Just remember to USE THE POWER!!!

And my personal thanks for being so dependable on posting. How many videos have you done so far? THAT'S what we REALLY need!

Miles -
As I recall, your truck uses the orifice tube/DPFE setup common on Ford of that era. (and if you don't know what I'm talking about with regards to DPFE -it's a sensor- and orifice tube -its what connects the exhaust to the intake through the EGR valve.) Poking around under your hood after reading Gadgetguys with gas analyzers - EGR / DPFE test - Groovy Forums thread and checking out some of the links in it will definitely get you started if not put you on the right path:

2007 f150 4.6 over 200,000 finally had plugs changed two were able loosen with out a wrench gapped new ones from 52 to 65 Ron suggested 85 I just didn't have the nerve. It runs better just no improvement on mpg maybe should have listened better.also intake is leaking a small amount of water just out of money for tinkering right now. Just wanted to post this last update.im loving all the new post.i may try covering the top half of the tb like I've seen suggested.

update 4-7-14 mpg doing better
on my 1997 chev 1500 350 vortec engine has all 4 O2 sensors replaced now, so with new double platinum plugs at .74 gap,, new plug wire,, used 16 aspirin with EverCler 190 proof grain alcohol running it thr 2 tea filters before putting in tank
When I started gaping plugs started with number 1 plug gaped until engine miss fired then back gap down 10% then gaped all plugs to .74 size, It ran great

It's me again .I have replaced the plastic tb gasket with a cut out cork one and my power is better and mpg is up some to. I believe the cork gasket does not block the groove any where the other did.i do need to close the gap on my plugs some I think my motors to warn for that part.thanks to all y'all who comment.who ever said take out the spacer was right for mine.i think I read about that in service bulletin. Y'all know theres something big going on if you read in there.

I also now have cover near half the entrance to the throttle body with aluminum tape we'll see what that does I haven't tried it yet can't find the picture I took of it
