wtf is wrong with my expedition!!

[2000eb]

alright now which 2 hoses are you talking about? the two that come into the tb on the driver side one above the other?

 

[designit]

I think he's talking about the two tubes that come off the EGR tube, along side the power steering cup / bracket & into the PVCS@#%&@ (something or rather -- a silver rectangular shaped (whatever) about 4x2 x 1" thick...

I marked mine before I removed them but his observation that one hose is shorter than the other & when switched around (wrong) the shorter one does quite reach is same condition on mine, so I think ?? he's got it right.

ya i just came back in from my truck and i agree i have always been able to reset my computer by disconnecting the battery though so not sure whats wrong there. but you gotta disconnect it for atleast thirty min i think i disconnected it the other day for like to min and my radio presets where still good so i doubt it reset my computer

 

[SunsetAZ]

ok well i went to emissions today and the guy told me i had to drive the truck more before the computer allows him to test it. and i went 35 miles today ( for no ******* reason) and my check engine light came on. im at the end of my rope with this thing.

 

[2000eb]

did you get a new code from the cel? give us codes and we will help the best we can

 

[SunsetAZ]

ok i went to autozone and got the codes read. p0306,p0406. cylinder 6 misfire, and insufficient flow egr. so in the past 6 weeks or so ive replaced the sensor, the egr valve, ripped off the throttle body or whatever that is and cleaned the gunk from the holes. replaced the gaskets. can of seafoam in the tank. im honestly getting to the point where i want to have my buddy lend me his scanner and ill put it up for sale and just flash it lol. this truck is driving me insane.

 

[jjbusa]

p0306 doesn't that mean you may have a bad coil.

 

[walnuts4x4]

yes any p030"X" is a misfire... and the last # would indicate which cylinder is misfiring... in his case #6 is

 

[SunsetAZ]

i already stated what they mean, and the parts ive replaced. can anyone help me. im really thinking about getting rid of the ford. ive never had such ****** mpg in my life and i used to drive a chevy with a 27inch lift.

 

[Explor2Exped]

i have a friend coming over tonight with his scanner and he said he is gonna clear it. he said unhooking the battery doesnt work.

Not true. My engine light stayed on after I cleaned out the MAF. I unhooked the battery & the CEL disappeared. If it does, your drive cycle is 150 miles & if the CEL doesn't pop up after that you should be good to go.

To fix the p0406 (I've fixed this) buy the EGR Valve & EGR Sensor. Stop messing with hoses & things just replace these two pieces.

For the other code I dunno because I haven't had to deal with that.

 

[SunsetAZ]

i already installed both of those pieces new. and my trucks running like shit and getting horrible mpg. like im talking ****** mpg. i had my friend clear the codes a few weeks ago and 50 miles later cel came back on and thats when i replaced the egr valve and went to autozone to get the codes read.

 

[Explor2Exped]

You installed a new EGR Pressure Sensor already?

 

[SunsetAZ]

yeah i replaced the egr sensor and the egr valve, and i pulled the top end off and cleaned up the gunked up holes. . still running like shit. if im driving for like 20mins when i pull into my driveway and put it in park the rpms shoot up to 2-3000 rpm. im so sick of this ford. i cant get one ****** bit of help.

sounds like your iac valve, clean it, also your tps could be bad, with a dvom check and see if it is set to around 0.98 volts, the tps is only twenty two dollars to replace, also, reset your ecu by disconnecting your battery

That's what I was thinking, the TPS...


Also make sure everything & I mean EVERYTHING is plugged in correctly.

When I was working on my intake I unplugged a lot of things, forgot one snap in, in the waaaay back of the firewall. It ran like complete shit. Revving up & down, almost stalling, also idling way too high.

So definitely check around & be patient.

 

[tmajikman]

I would suggest you check the elbow at the back of the intake, it causes all kinds of idle and mpg issues, also, take the black cover off and look on the passenger side of the tb, inspect all your vacuum hose and pull your pcv valve and make sure it rattles, if it rattles its good, if not, its bad. When I got my X almost all of my vacuum hoses were collapsed, you can buy a few feet of rubber hose and go to town and replace them for a few bucks. You can get the elbow from NAPA for much cheaper than the Stealership ($13) from Napa.

 

[SunsetAZ]

ok i dont know what you guys are meaning. . spell out what these things are. pictures would also be great. im an upholstery guy not a motor guy, but i am confident i can continue to work on this expedition.

 

[SunsetAZ]

ok i checked the tps and it said 4.8 wtf

 

[walnuts4x4]
