Rather than drain the coolant again to get the sensor out to test it, has anybody measured the resistance curves on stock Chrysler sensors out of a mid 1990's 4.0 I6?

Or, maybe, somebody have a link to the info?

I don't know about my wife's 2001 Corvette, but I know my '94 Defender has no EGR valve and just passed emissions with absurdly clean numbers for an early 1960's engine design with a hack-job factory EFI. (IIRC 7ppm HC and 0.00% CO)

I also know that the Jeep 4.0 hasn't had an EGR vavle since 1990 ...

Most EFI Land Rovers up until I think 2001 were all bank fire as well. The Lucas 'Flapper' and 'Hot-Wire' systems definitely, I believe the GEMS as well. The Thor-Motronic.... I don't know for sure.

Ok, almost ready to connect up the fuel lines to the rail, but I have to ask.

How the heck to these Jeep/Chrysler push-to-connect fittings work, and where can I get the fuel line side of the connectors? 93 Cherokee fuel rail with the integrated regulator.

Wow, took me forever to find a picture that showed the point I needed to see. It appears that yes it will, but new holes will need to be drilled for 2 support pins. These holes need to go in the webbing underneath cylinders 1/2 and 5/6.

Hmmmm... I might have to grab one off of e-bay and try it ...

I am wondering about this. I know that people are using their stock 258 manifolds when they do a 4.0 head swap. Does the 4.0 manfold fit on the 258?

I am trying to figure out exactly what was changed when they went to the high-port 4.0 heads. It almost appears that they left the intake bolt pattern ...

Even better if you want to practice would be to pick up a cheap hobby kit from Vellman. They make all sorts of gizmos like LED blinkers, little robots that roll/walk around the floor, clocks, FM transmitters.....

Some of the cheaper kits are in the $10 range or so, and are great to practice before ...
