Runs a little rough, check engine light is on, but feels like there's no power!! Exhaust fumes are REALLY bad. What is the best way of pulling a code on this heep, and knowing what it is without paying the man$$$$? Is there only supposed to be 1 O2 sensor, does it matter if there is no cat???? Sorry for all the?????'s Im trying to make a once parts jeep a road worthy dd, see pics. Thanks guys

Alright, thanks, anyone got something for the other gripes!!!

 

Replace cat, that will help with the fumes.

 

Check your timing an if the plug wires are on the right cylinder make sure all sensors are good and working correctly

 

start with the check engine light. It could be running really rich causing a strong exhaust smell.

 

So, i only have 1 O2 sensor on this, isnt there supposed to be two???The one i got is just aft of the collector of the exh manifold.

 

I know 95 has only the front one.the 2nd O2 might of came in 99 with the newer intake?I'm guessing on this though.
