87MJTIM

I had parked mine overnight at my office. I came back in the morning to find a hand written note. It said if I was going to sell it to call the number written on the note. I never called, but I still have the note. In the past, some people have asked if it was for sale. I politely state that it is not.

Old dogs can learn new tricks. I did not know that.

Why does the cover of the 90 catalog list "YJ" (which is the Wrangler) then list Cherokee, Wagoneers and Comanches by their model names (not letter designations). Does the catalog show any Wranglers?

the master cyl is the issue, not the slave. the slave doesn't matter if the trans is pre-98. The bolt holes in the firewall are the issues.

Or I've had it wrong for 31 yrs!

Is the grill up-side-down on the last photo/poster?

Sensor ohm test pin A-B - 4.5 ohm bad sensor?

Thx

An internet search keeps coming up with NGK and NTK as the same parts. Are these the same?

Follow up: With a DVOM, KO/EO - Tested the orange wire (pin A) from the heater relay - got 11.8v Tested the gray wire (pin C) from ECU - got 5.01v Ohm tested the ground (pin B) to engine block - 0.000 I found this on NAXJA for a reference. http://www.naxja.org/forum/showthread.php?t=1012701 I'm open to suggestions.

All good points, Agamble. One observation, the 98 master cylinder is taller, longer, and the bolt pattern are diff from the earlier master cyl. I remember reading that the 98+ master cyl will interfere with the brake booster or intake ( I don't remeber which).

Proper matching tcase - 23 splines. (If you are going to 4wd. If not - Never mind.)

Gonna get the DVOM to it this weekend. I will post the results.

the O2 does change, but will read <2.5v most of the time while cruising. While idling, it will bounce around +/- 2.5v. Before I swapped the O2, the signal was 4.98v - flatline.

When in OL, FT is 128 short term. REM show lean.

As my signature states: 87 4.0 Laredo. I have Nick's REM to give me readings from the ECU. Lately, the engine is running stuck in open loop (OL). I have the REM set to display engine temp., Open/Close status, O2 volts and (something else). I start the truck up in the morning and let it run for a few minutes - 2 to 3. The REM shows it switched to CL. I start to drive away and it switches to OL. It will remain in OL. It does not switch back to CL. The ECU came out of a 90 XJ with a 5 spd. The O2 sensor was replaced last fall with the NKG, or whatever # Cruiser states. The O2 volts at start up are 4.+ volts. I can watch the volts drop to ~ +/- 2.5v when it switches to CL. I will drive only a short distance when it switches back to OL. The O2 will stay at or below 2.5. The O2 usually reads below 2.5 most of the time. The engine temp per the REM is at 185* and below while moving. At idle, it will rise up in to the 190s. Once I start to move, the temp drops back down. Before I pull out a parts cannon, does anyone have a suggestion on where to start my testing? The Renix fuel injection manual only describes how the system works in a perfect world. It does not give a detailed trouble shooting guide. I am going to replace the t-stat to address the temp issues. What about a CTS? (Part # for a CTS?)

Perhaps Ted Kennedy should have driven one of those....

Nickintime has a lot of videos on his 89 XJ. He shows from when he got it and all the modifications he’s done to date

10 slot...but I'm biased

Maryland used to do a roller test. It stopped that and did a tail pipe test for non-OBD2 vehicles. This year, the state is eliminating emissions testing for pre-96 vehicles.

You posted while I was typing

The one they gave you is for cruise control. The metal thread screws to a rev counter for the cruise control. I don't know it there is what the part number is for the one w/o cruise.

Mine came with both light and key buzzer/chimes. The module on mine is black and has not worked in years. I pulled a blue module from a 93 parts XJ. Will the blue work in the earlier years fuse box?

I don't have the build sheet, but the window sticker included "console with armrest $118.00."

If you count my wife who purchased it before we got married, then yes, original owner. Oh, I still have her, also.
