[pwrliftin]

maybe, I'm not totally sure. if it is what do i do to fix it?

[freakjeep93]

yours is a 86 right? if it is and you have the 2.8 make sre the carb is adjusted right. if its got the 2.5 it might need a sensor or something :dunno:

OK, back up...

 

WHAT did you "fix"? What where you attempting to correct and what where the symptoms.

yea its a 2.5. i replaced the plugs, wires, cap and rotor, new fuel injector and tightened up my intake bolts. not so much fixin but replacing :nuts:

[CWLONGSHOT]

IIRC the 2.5 4 cyl is TB injection? If so, there are no injectors as on a 4.0L.

 

Someone correct me, I haven't been under the hood of a 4 cyl in some time...

 

Did you mean fuel filter?

 

In any event, retrace your steps and take nothing for granted, remember these things are getting old, sometimes hoses can disintegrate form age and higher under hood temperatures.

it has a single injector, at the throttle body i believe. the filter is next. my friend said i might need a new exhaust manifold cause mine may have a leak in it somewhere

The '86 2.5L is throtlle body injected. The injection/ignition system, although throttle body rather than multi-port, is based on the same Renix system used in the early 4.0L trucks (and XJs). The fuel-air mix is controlled by the oxygen sensor, which is located in the exhaust pipe (or manifold, don't recall for the 2.5L). If you smell gas and you're getting black soot from the tailpipe, you're probably running very rich and a bad oxygen sensor would be the first "likely suspect."

i considered replacing the 02 sensor a while ago but everytime i ordered the part online they sent me a single wire instead of the 3 wire. i tried autozone but they don't carry them so any ideas on where i can get the 3 prong plug? :dunno:

:doh: special ordered one from autozone, 80 friggin dollars. man i need to shop around more :shake:

[pwrliftin]

02 sensor=replaced

truck=runs soooo good now, but i need to sell it before i go to college

 

comanche to a good home?

[CWLONGSHOT]

I'm glad you fixed it, but a bad O2 isn't gonna make it smell of gas. What did you do to fix the gas smell?

[pwrliftin]

Thats it. Maybe i got lucky and bumped something while changing the 02 sensor, but to my knowledge all i did was swap the sensor and it stopped

[kastein]

You have to sell it?

 

Where do you live? :brows:

[pwrliftin]

NE Ohio, like 15 minutes south of akron. I gotta sell it so i can have some extra cash to fall back on while at college, but when i graduate and start making a living I'm buyin another :yes:
