What does this vacuum mean?


How in the hell could I do that without setting codes!? I hate computers... Why not just a simple old distributor.. I know how to time that!

Not every misfire sets a code. They do all leave a foot print in the computer's record, which is called "Mode 6" (engineers, not intelligent people, made this stuff up).

Mode 6 would tell you which cylinder(s) have a problem.

Also, there are a few reasons for coil packs vs distributors. You can do a lot of trick stuff with an EDIS system, and do it pretty cheaply, that is really hard (reads "really expensive") to do with a distributor.

Also, after they go to EDIS all Ford engines have a factory MSD system.

Well it's basically all new plugs and wires. (10k on them) so where could my issue be? Also when I did the cardboard test it didn't suck it back however I noticed it would push the paper differently.. I'll have to post a video of my exhaust.. Could that be helpful in finding the issue?
 
If you have seafoamed it lately I have seen it coat the plugs with a glaze that will cause a miss, Also on the cam sensor the timing could be off just a bit and cause lower vacuum, but not the miss that you seem to have at idle.

Yeah I noticed ever since I rebuilt it.. (I bought it with a rod knock so I have no idea what it was like before). I'd ask people around me who are mechanicly inclined and they all say oh yeah that's a pretty good idle.. I'm just like no it isn't! It's pretty bad I always thought
 
Well I re positioned the cam sensor/synchro according to the shop manual again.. When I set the #1 to tdc and took off the sensor before removing the synchro, I could see that the little metal thing inside was opposite of the cutout (although not direct). So I pulled her out, repositioned it, used the tool to make sure the little metal thing lined up with cutout. And put it back together. Still about the same idle quality and the vacuum is the same
 
Have you tried to narrow it down to a specific cylinder? if so its time to pull that plug, wire, & finally the injector in that order, 1 part at a time and see if that makes a difference swapping the parts to another cylinder and see the problem move or with another known good part.

Yeah I'll give that a shot after work and let you know how it goes

Sorry it came out weird.. Let me know if I need to explain anything.. It was in table form and I figured it would paste that way
 
Well I just figured out CID $53 tid $07 and $08 are irrelevant since I don't have 8 cylinders
 
Do you have an EGR or DPFE valve on that truck? If so I would start checking either of them, Yes you can ignore the 8 cyl codes but I am really wandering why you got them reported to start with, Have not seen that,

JP02XLT
 
Oh I did some research and it said that happens for some reason.. (Engineers are retarded).. But yeah I replaced the dpfe sensor, but I'm doing the hoses next and seeing if that fixes her
 
The $00 $21 one I read is indicating I have low vacuum or pressure (however it's measured) in my gas tank.. Fuel cap?
 
Just another question, I read that these 3.0s don't like autolites plugs which is what I got. So I'm replacing them with motorcraft plugs. I have ngk wires with 10k on them. Should I consider replacing the wires with motorcrAft wires too or are the NGks good? I always thought NGK was quality.
 
could be a fuel cap, could also be a hose leak, those are a pain to find unless you have a smoke machine. I would try some vaseline on the o-ring of the gas cap and see if that helps. Plugs, I use Autolites in my supercharged ranger, and they last longer than anything else, I would check the wires close, I had a Lifetime Napa Belden set go bad around 10K miles as well, slight miss under acceleration, only symptom it had.
 
I'm gonna try the Vaseline and see what happens. However I have some pretty upsetting news. I looked at the cam synchro position tool that was provided with my new synchro and have concluded that the tool doesn't align the synchro in the same direction as the ford reccomended part. You can see in this photo how the sensor offsets the little metal thing inside (the thing the sensor reads). A little to the left it the tool were set upright. My alignement tool sets it in the center (and even a tad bit to the right, could just be me though). I'm pretty pissed at dorman for supplying me this crappy part!

Does anyone think I could have caused engine damage with my sensor being out of alignment for so long? I've been hearing a little knock at idle... :(
