94 4.0 dogin it

[chelseasman2008]

hey all i got a 94 exploder with the 4.0 ever since i bought it its been a gas guzzlin dog! i got new plugs n wires n a KnN filter no muffler but still have both cats any ideas? its doesnt even like to spin tires in the mud while in 2wd and no not good lol is there something common?

i had a 91 n a 92 before and and the both ran like champs!

sounds like the exact reason they call them exploders. idk personally i have never liked them. my mom has owned a couple and driving them compared to my ranger is 2 different worlds. hers have always ran like hogs.

Check your O2 sensor readings and clean your MAF. Change your fuel filter, then check your pressures while running.

I had a 92 Explorer once upon a time. It never sucked the fuel like that, but it DID however lack in the power department. It wouldn't rev past 2100. After a short time period of utter confusion, I was thinking "It's probably going to be something stupid simple."
Take up the slack in the throttle cable! Maybe not the same problem, but check that anyway. Could solve one of your problems...

how bad is "guzzles gas"? my co-worker has a 4.0 (ohv) w/ AWD and he gets about 22mpg on the highway and averages about 18mpg overall, but his is a 2000 with 208,000 miles on it. however, he can still chirp the tires before the AWD kicks in, so he has power and decent economy. I dunno if he's lucky or subpar, btu thats my only reference with a 4.0.... me and my friend with rangers have 3.0's.....

its probly only geting 12 mpg its bad! i cleaned maf and no change, it will rev up fine but there is just no power doesnt miss or anything idk shoulda took it in for cash for clunker!

 

[adsm08]

I'd still be looking at O2s and Fuel stats. It's probably something simple. If the O2 is giving bad readings it'll dump fuel and too much fuel will make it dog it. Puts out the flame. The MAF may still be your problem as well. It could just be plain old broke instead of dirty.

 

[chelseasman2008]

is there a way to check the maf ?

ok another qestion would the front wheel bearings being totally shot not let my 4x4 kick in? i have no lights or nothing and i also tryed a new push button

 

[Andres629]

Not usually. Check your 4x4 control module. It is located in the back left portion under the plastic. Take the cover off to expose your window washer fluid and such, and when you look in there, you should be able to see your module. This could be bad, or the wiring into the harness corroded. I'll see if I could find a picture somewhere, or if someone has one...
