Man that motor looks so nice and clean. Something about a new fresh engine that gets me worked up.

So then the coolant sensor will read a lot cooler on the radiator side of the thermostat than it would if the sensor was in the block just below the head. Because the 1990 renix was designed with the sensor in the block and if that spot is hotter than the radiator side of the thermostat than...

I cant prove it. It just seems logical that the temp in the block would be hotter (where the coolant sensor location), because that's where the heat is generated (cylinder head). The coolant at the other side of the thermostat is cooled by the radiator. Block side = hot [[thermostat]] sensor...

The 1990 renix coolant sensor is in the block reading coolant temp which would be hotter than the coolant at the thermostat housing. The 1991 coolant sensor is in the thermostat housing reading coolant temp which would be cooler than the coolant in the block. Question: What Change on the 1991...

Re: Guess what? I have a RENIX XJ with a rough idle and misfires! The automatic TPS four-wire connector A,B,C, and D, how do you back probe and test D when there is no wire connected to D?

Talked to Bosch today and was told that if they changed the white porcelain o2 to a metal body, and if its the correct one (purchased at an approve retailer), there should be a number on the sensor body. 500E263073.

I installed a white porcelain bodied bosch 12009 sensor that replaces factory P/N 4713639. Tested 5 ohms. Had no more than coupe hours idle time due to engine diagnostics testing. Then the engine began misfiring real bad and wants to die and running vary rich. retested ohms reading on o2 and...

Is the newer bosch 12009 still working okay?

The walker 250 23501 ceramic o2 is no longer ceramic. Had to send mine back.

The DBR ll is a different tool than the MS1700.

Did you ever complete your renix data reader?

Is anyone familiar with all the components needed to make use of the DRB ll for the 1989-1990 jeep Cherokee engine and transmission? Also, I've heard of so called super cartridges around the net but don't know what makes it a super cartridge over the other cartridges. thanks in advance for...

So what are the major repairs that have been done to have kept it in drivable condition over the years?

Did some research and I'm thinking it has something to do with the sync signal generator in the distributor. Anyone concur?

Sorry, I meant fuel Sync!
