HELP !!!! having problems with my exploder & it my D.D.

[mustangsrus]

1st off thanks in advance for any help !!!!


i have a 95 limited 4x4 4.0 OHV auto ( current mileage is 100,088)
only has one mod ( k & N c.a.i. )

it has a weird intermittent bucking & shaking. with a serious lack of power. & sometimes it just doesnt have any power.
other times it drives perfect good power & trans shifts great.
i checked the fluid it a couple days ago & its perfect it was changed @ 80 K

i changed all plugs wires, pcv ,coil packs, fuel filter,NEW FORD I.A.C. & all fluids & transfer case service o2 sensors @ 80 K

and dont know if this matters but its still got the stock exhaust from the manifolds all the way back

How long has the K&N been in, was the oil bled off the filter prior to install, and has the MAF been cleaned since it's been installed

 

[tgreene92]

id defintely clean the MAF as well as all other important electrical connections. you could also have plugged cats, i had the same symptoms as you with my 98 xlt and after i cleaned the MAF and gutted the cats those problems have been non existent for about 3 months. id also clean and or replace your idle air control valve and hit it with a treatment of sea foam.

 

[mustangsrus]

the k & N has been on for about 8 months now & yea its been cleaned once since then. i guess i could clean it again & o`yea the IAC IS NEW SORRY i forgot about that !!!
i will try it & get back to ya

 

[mustangsrus]

well i`ll update you all

i cleaned the maf. it was fine for a couple hrs then went right back to acting up so i talked to a mech friend who deals in old trucks & he said something about a barometric air pressure sensor possibly being bad & my maf was bad also so i unplugged the maf. & started the truck & it ran pretty close to perfect & then drove around the block ( as i was told to do ) it didnt buck or heistate or jerk me around & had lots of power

so tomorrow i`m going & buying a B.A.P. & a M.A.F. ( i`m guessing a BAP is like a air intake sensor on my 03-cobra )

will update you guys tomorrow

BAP sensor:

 

[mustangsrus]

oh ! ok thanks so basicly what does it do ?

 

[Joe Dirt]

Measures barometric air pressure. If you didn't have one, your fuel mixture would be off depending on the air pressure of the ambient air.

 

[mustangsrus]

ok thanks joe ! & update i got the new MAF installed & it acting better !!!! but couldnt find where the BAP was on my truck. & it still shutters a little bit but has plenty of power so i`m off to find where the BAP is hiding tomorrow LOL

Not quite the 50 hp increase you expected from a cold air intake huh? I don't understand why anyone would deliberately place oil upstream of the MAF. Glad to hear you fixed it.

 

[mustangsrus]

yea i knew it wouldnt be either but i got it for 110 shipped & yea i feel the same about the oil too !!!

but its not fixed yet cant find the freaking BAP/MAP sensor location on the 95 v6

 

[wicsmith1997]

Fuel Filter? Have you changed it recently?

 

[1998Explodasport]

ok thanks joe ! & update i got the new MAF installed & it acting better !!!! but couldnt find where the BAP was on my truck. & it still shutters a little bit but has plenty of power so i`m off to find where the BAP is hiding tomorrow LOL

[mustangsrus]

Some of the older models the bap/map is hidden in the firewall all you will see is the electrical connector you can refer to this thread for help http://www.explorerforum.com/forums/showthread.php?t=241541 Good Luck
