You have the 21lb correct?With those did you have to cut wires or is there an adapter to switch them over.I am not looking forward to this If i buy new injectors,Cops,and plugs it is going to cost me quite a bit.How much are those injectors?I am going to let it learn the A/F ratios and see if it still does it on level3.If it does i will increase the WOT fuel and see if that helps.

 

Nope, I have the 19's - Type 3's and I use a 4six Crown Vic harness w/ twin blade connectors..I believe you can get connectors on the motorcraft site..

I acquired the injectors and harness from a Romeo crate motor..


Look at those connectors ...

 

Ya i saw your intake you made.So you have the 19s also just a diff design and are feeling it bog the same as me.I am going to look around at the 21s.Is yours doing the same as mine just at take off when you go wide open?

 

Yeah, Freakin Bogging - have to feather it - I think the silencer is about 2" ID on the stock intake at the narrow point and I'm at about 3" now - I might just try 2 1/2 and see what happends..

21's might do it for yuh or a little higher to be safe, I think the 3 valves have 26's (04's) - stock..

It's going to be hard to find 21's cheap but good luck..

 

Just an update.I rebooted computer and increased WOT fuel by 50% and it is a little better but nothing like it was before the intake.I am going to go back to level2,where it was prior to intake.I have my previous 0-60 times for that level for referance.I will start messing with WOT fuel on level2 and see what i can do.

jbrew,those injecters are around $260.Do you think i should go ahead and order new COPS from global and get some new plugs or am i better on spending the money on injecters?This Sucks

If it keeps it up i might take it back off and see what happens w/ the stocker

 

Kev - hold on there... befor you spend $$$ on this.

First - injectors are not the answer. The stock 19# units will support approx 320 crank hp before maxing out on a 5.4L 2V. Additionally, if you bump up the size of the injectors you will need custom tuning to accomodate them properly. The PCM is calibrated for 19's. And, you will no longer be able to run a stock tune, or use the Edge due to those larger injector giving you driveability grief.

~Oh Jbrew ~ - 5.4L 3V's have 24# stock.

Proper fueling is not a hit & miss thing to be guessed at. It's also much more complicated than just arbitrarily adding fuel in open loop.

The vast majority of AF1's on pre-04's run perfectly on either the stock tune or a canned tune such as the Edge or Superchips. I know - I've had one on my ole Y2K - either stock or custom tuned it was perfect.

So that leads me to believe there is something else goin' on here. Check the install, vacuum leaks, etc ( you already cleaned the MAF).

I would call TP asap to discuss - they will know what to do as they've pretty much seen every failure mode. Also this is clearly a tech support thing, which is handled by direct contact with the vendor.

BTW - someone mentioned a Mode 6 test for misfire histories - a great idea.

Just tryin' to help.

JBrew's an old hand at this and way over my head, but if he starts advocating the use of dat SeaPuke chit, run away LOL!

Mgdfan,i am not really sure what to do.I haven't tried but i can almost gurantee that if i put the stock intake back on it will run stronger.Like i said the intake works great at all rpm's except when you stand on it from a stop.I can feel bogging down like its not getting enough fuel.What is a mode 6 you are talking about?I called TP today and mike wasn't available,talked to annita.Anyway i know the AF1 isn't supposed to do this and it may not even be the intake,could be a diff failure.I don't really know where to start and i also don't want to start throwing all kinds of parts in it.I can not make it kick a code either.It just feels like it is running lean under extreme load.I will go back through the connections tomarrow but i have looked it over several times.
I appreciate your help and am open for suggestions

 

If i cheack the install over, run it and record my times.
Then replace it with my stock intake and run it for times.
I think the stock will do better and if it does then what?

 

Kev - you bought the AF1 from them right? This entitles you to some tech support. Call 'em leave a number where you can be reached and request(insist) on a call-back. It will happen.

A Mode 6 is a special type test using a more sophisticated OBDII scan tool. A well-equipped garage (and of course your Ford Dealer) will have one. If you've got incipient/transient lean misfires under load it will pull them out, hopefully.

A good diagnosis is crucial; you do not want to just throw parts at it. It could well be an injector/COP problem - but you need to isolate it.

Good luck.

 

Yes, i bought it from TP.If i was to do the mode 6 test would they do this with my edge installed.So i should put a few hundred miles on it so all of the A/F ratios relearn then get this test done.I should also leave the canned tune alone and run it without adjusting WOT fuel.My next question is if i do this will it say if it was like a bad injector or not?If i leave a call back for TP the thing is i can't say for sure wheather it is running lean or if its something else

 

Kevin , use Seafoam to clean your MAF

HI BUBBA



Actually MGDfan doesn't know what were talking about . I pulled my breather line and added more fuel in with the mix - No bawg - So it's definitly a fuel problem..

Writing Troyer is a good Idea or just call - Crystal will patch you threw if he's around..

 

You crack me up jbrew Look on the bright side jbrew you may end up getting your shinny intake that you want cheap if it pisses me off much more
So you used additional spray at WOT and it stopped huh
I'm tired and have a headache from thinking to much LOL so i'll cheack back in the morning

 

Yeah , I did the breather deal today - It wasn't my idea - buddy who has an 05 had the idea so we tried it. Squirt bottle tube and allot of ducktape - mann I hope no body saw us, we went thru three triggers on the bottle, gas tends to shorten there lives

Maybe I shouldn't of wrote this, MGD will prolly give me more chit now

BTW , I never actually did the SeaFoam - Intake treatment myself , I don't believe in it - I take mine apart and clean by hand - I just heard from allot of people it worked..

Anyway - @ WOT , we could keep up with it a short time - about three full good reves and it sounded awesome with the added fuel - it was sucking pretty hard - I thought it was going to pull the filter inside out

Seems to be a definite fuel prob (my injectors aren't even a year old yet) - if MGD is right by chance, the MAF's chumping me....

I wouldn't do nothing yet Kevin , wait in see what others might have to say about this..

Mode 6 is just a history reader/reporter and most likley won't help in this case - we don't have misfire issues or injector problems, besides the new COP and Injector probing tools you can purchase youself for under $100 a piece eliminate the need for mode 6 for me.. ..

It could be computer related tho, we could be outside of parameters and theres no code for this kind of fault.

320 crank HP for the 19's - I need to see this data, that would help.. To me that doesn't matter, when your under a load going up hill - your motors going to require more fuel @ 260 hp going up hill vrs down @ 260 hp.. who cares about the crank ponies..

 

MGDfan is gonna be on your a$$ for sure Allright i'll hold off for now and quadruple cheack the install.Call me cheap but i hate paying the dealer.If worse comes to worse i will just use my stock intake and drop in a high flow filter and use that set-up.It is weird though b/c it has better response everywhere except when you stand on it.You hear it take a big gulp of air then Baaaaaaaaaaaaaa

 

Hi Jbrew;

Nah.. I'm not gettin' into a pishin' contest with ya - I fully acknowledge your experience & the fact that you got big brass ones - spraying raw fuel into a running engine by hand ... wow

On the injectors - here a couple of posts you two should read:

Kev - talk to MT; it will get straightened out. Don't discount lean misfires just yet; Bluegrass made a compelling case for that earlier. You may need to spend some $ for diagnostics, but let MT advise you there.

Good luck.

J - you crack me up!
