unless you can view PIDs are you just going to be throwing stuff at it hoping it fixes the problem.

would i have to "relearn" the ecm after i cleaned the MAF sensor??? maybe if i go unhook the batt. for 15min like the manual says it will clear it up....anybody know????
Worht a shot. I doubt its EGR, but never know. Mine threw a trouble light, but NEVER nocticibly changed how it ran.....

reseting the comp. didn't do shiza....owell, on to plugs and wires i recon'....the damn egr costs like 80bucks, so ill try that after plugs/wires.....again, there's no trouble codes at all...so hopefully it's a plug fouling out or something....thanks again ya'll

may sound dumb, but does the check engine light actually work?

good point. cycle the key, see if it lights up. If it doesn't its required to!Jason4x4 said:
I'm really thinking its time tot ake it to a shop man. Like I said, you are just going to be throwing part after part at it until you luck into the right thing at this point.
Do the plugs and wires though. At 77K there is no reason not to. Just don't buy crap. I hate how often I see junky plugs and wires come through on car. A tuneup with junk parts might as well not be done.

have you checked all the connectors in the engine comp? maybe something came undone. i would be careful with that maf too. they are a pain on fords. also have you checked the battery voltage and alt output levels? thats the first thing they will check at the shop. just food for thought.
sounds electrical to me. i would mess with some stuff and see if it gets worse or better

well, i just talked to a GM tech at my dads stealership and he said fuel pump, or cat is clogged....but why would that make it get worse under load...he said it happens all the time on GM"s...and doesn't throw a code
so im gonna go get a fuel pressure gauge and hook it to the fuel rail and test for pressure there.
thanks again ya'll.

"happens all the time on GMs", not on Fords. Fuel pumps usually just die on Fords, not slowly die and put out too little fuel pressure. Thats a Chevy thing.
I have only seen 1 Ford in my year at the dealership that had a fuel pump issue other than just being dead. I worked on it myself, it was a Super Duty that just wasn't puting out enough pressure. IT was fine at idle, but under load the fuel pressure was taper off just enough to set off fuel trim codes. Didn't even spit and sputter, just tripped on the check engine light. And its so rare that when I said it needed a fuel pump for that reason, one of the senior Ford techs took the job from me and told me I had to be wrong, that never happens, "if it were a GM I could believe it". He tested and found I was right, haha.
Pull the upstream O2 sensor or sensors. If it runs better, its a clogged cat. But I doubt it. If it seems to be a clogged cat, GET IT BACK TO THE DEALERSHIP!! Catylitic converts are covered by an 8 year 80,000 mile Federally Mandated warranty, and with how many miles she has, shes close.
Send me that VIN anyway, I will run it and see if there are any outstanding FSAs or Recalls. You never know, there could be something blatant that needs to be done.

oh yeah, and it won't rev up past about 3200RPM...it acts like there's a redline there....also, there is a very very decent amount of water/???? coming out of the exhaust, and some is dripping from the muffler itself....
i did forget to mention that two days ago i sea foamed the truck, thinking it was carbon build up or something and it smoked like a motherfu(ker and some smoke was coming out of where the exhaust manifold meets the downpipe...like it was being forced out there or soemthing.....that makes me believe cat.

redline thing sounds like a clogged cat or an ignition issue.
Water is likely just the weather. Has it been humid or cold?
wish I could be more helpful, so many things go through my head every time I try and Diagnose something I can't help but just randomly throw out thoughts.

haha...well, ignition is completely replaced....coil,plugs,wires...
and the cats, well, i unhooked the o2's and it ran like a champion...no biggie...the only thing i think it could be is a head gasket or something since there's no SES lights and also, it won't rev about 3k, but at 3k it spews something serious out of the tailpipe(and dripping from muffler) tried to ignite it and it ain't fuel, but it doesn't look like coolant either, it looks like just water, and there's ALOT of it too...not from the weather. anybody got any more clues???? thanks again ya'll..
oh yeah, coolant looks fine, a little brown, but fine...and oil looks good too, how can i tell if it has coolant in it??? would it be very noticeable???? thanks ya'll

How old is it? I may have missed it....any warranty? I have a solution
. We recently did this to my buddys aunts Mountainer. Drain out most of the oil, leaving a little under a quart. Start the truck back up, open oil fill, drop in some sand, and a few pebbles
, then rev to about 3500 RPM for a few minutes, until you start hearing some squeaking, clacking, or other strange noises
. Break the oil fill dipstick right above the fill line. Pour two quarts of oil back in, and bring it back to the dealership.
If none of that applies:
and a
and watch it go BOOM.
After all, it`s only a F*RD, you`re not losing much
On a serious note, I`m PRETTY sure your coolant shouldn`t be brown..head gasket ok?

yeah, it's not really brown brown, it's green with 80k on it...so a tint of brown is there..but it's mostly green. what about bad gas???? she got gas the last two times at the same spot...local BP. anybody know how to test that??

you removed the O2 sensor and it runs like a champ? Didn't I say thats how you know its a clogged cat? You took away the massive backpressure and it runs good. I have seen clogged Cats blow headgaskets(or the other way around, I can't say which for certain) but either way I've seen them related before. Take it to the dealership man. If it has less than 80K miles on it, Cats should be installed under emissions warranty. Then go from there.
There are 2 tests to determine head gasket leak, cooling system pressure test(you can buy the tool at some Sears hardware for a decent price), or a Combustion gas detection test. Thats not such an easy tool to come by. I actually don't know a single tech that has their own. Its not really expensive, just not common. It checks for combustion gases in coolant. So you test the coolant and it goes all CSI letting you know if there is combustion gases present(indicating head gasket leakage).
But if the plugs looked fine, their likely would have been one really bad one to indicate the problem. I'm really leaning towards the clogged cats being THE problem, especially if I read your post right.
