Hello,

I'm Mat, from Poland.
I'm owner of a 1990 renix Jeep XJ.
Hate him, and love him at the same time but my love is loosing recently....
I hope you guys can guide me with fixnig it.

 

What needs fixing? There are a few of us with the Renix-engine Cherokees who are quite familiar with them.

You sure are a long ways away. Or, visa versa for you I suppose.

 

Hello,

Mostly it's lack of power and im doing 5 MPG at the moment...
Engine is rebuilded, transmission is rebuilded, tps/map/o2/cps sensors are new, coil, spark plugs, wires etc all the ignition system is new even the distributor.
No matter what i change or di in the engine there is no changes in running.
I'll later start my topic in correct section.

 

Welcome.

That's pretty terrible mileage. I bet some people here will be able to help.

 

Could be a plugged catalytic converter(s), you could try temporarily removing the front oxygen sensors to see if that resolves it, if so you'll need to replace or chop out the cats
