I had the same problem with sputtering and back firing through the intake turns out my fuel pressure was too weak if i were you i would verify fuel pressure

 

kool gotta go

 

@freegdr thanks again
@purple xj how do i check the pressure, special tool? im on a verry limited buget. what fixed your problem?

 

vacume lines cleaned and replaced. terminals cleaned. thinking it might be time to mess with the fuel pressure.

 

On the fuel rail theres a schrader valve rent a fuel pressure tester from autozone or buy one if i remember you should have around 39 psi

 

the schrader valve is that the thing the vacume line plugs in to?

 

no it looks like this ,this pic is from a 95 yours might be in a different spot

 

valve located and advanced has a gauge, lol gotta wait till after 5 to get a ride to town to get them. so if the pressure is not up to spec is it the fuel pump or a regulator or some magical demon pinching the line?

 

what results did you get here

 

12 AND 55 all the others cleared

 

thats good a bad fuel filter will also cause low pressure have you ever replaced it?

 

i replaces some odd stuff a couple weeks ago, the battery, spark plugs, o2 censor, oil and filter, as well as fuel filter and the air filter. unless it has clogged in 2 weeks (had the tank out and its clean inside) i think its good but im not sure.

 

filter is most likely good see how the pressure test goes

 

lol had a little extra cash and wanted to give a little TLC to my xj, oh the irony that it breaks down now....

 

see if you can rent a gauge when you return it you get all the money back autozone rents here in fl
