I have compiled 25 of my "mostly Renix" write-ups in the XJ write-up section.

They are in a somewhat priority order, especially for the "new" Renix owner.

Here is a link to them and also an outline of them:

You da man Cruiser! Great collection of information. All RENIX owners should bookmark it.

Thanks to you, Mr Walker for contributing to it. Much appreciated.

Impressive!

Years overdue, too!!!!!

Thanks Cruiser. Got any tips on renix gas mileage?

cruiser54

Absolutely. Get a commuter car!!

Upgrade your injectors to the 4 hole design. Have a new headpipe made that swoops back in two 45* angles instead of a 90 and without the "crush" in it.

Well I have been driving with 8mpg for months now. I don't mind 12 MPG but 8!!!

Bad O2 sensor or poor vacuum connection to the MAP?

Any other driveability issues?

NorCalJeep

Replaced O2 and did tune up. Runs a bit rough. Send me a PM what i should check next.

Excellent!
This write-up is going in my notebinder.

Let's use this thread for everyone's sake.

I say start at #1 in the write-ups and work down to at least #5 for starters, minus #2.
#11 would be good, too.

Kinda like ordering Chinese, huh?

cruiser54

Thanks. Enjoy your Jeep.

NorCalJeep

Thanks. I try numbers 1-5 and 11 lol
