87MJTIM

Does it start and run if you give it gas? if so, could be the IAC.

60? Such a youngster. If you take care of it, it will last another 340k.

Who won in Comanche class?

Thanks for the cookout, Nick great to to meet other CC members.

What a "Motley Crew".

I should arrive 10 AM (approx.)

Jed and Jethro Clampett must be driving. Grannies' rocking chair is up on top.

I have (accumulated) 4. Two 87-88(1 manual [original] and 1 auto) and two 89-90 (1 manual [bad?] and 1 auto).

I have the REM scanner in my truck. I had the O2 volt, Open v. Close Loop, ST and LT fuel trims constantly displayed. The O2 volts was constantly around 12v. At start up, after approx. 2 min., it would switch to closed loop, then quickly switch back to open. There it would stay. Naturally, I thought the O2 sensor was bad/going bad. I joined in on another thread about O2 sensors. I had recently replaced it approx 1 ago. I thought it couldn't be bad, yet. Based on feed back from Ohm in the thread, I tested the sensors that tell the ECU to switch to closed loop: MAP, MAT, CTS, and the O2. I changed one of the displays to show Rich/Lean. It constantly registers Lean, and would not switch to Rich. I used the Renix Fuel Injection manual and www.lunghd.com for proper testing steps. All of the readings registered within the normal operating ranges. (I didn't write them down, but used the scales from the two sources. SO DON"T ASK ME THE READINGS.) Since all the readings came back "normal," I looked upstream at the ECU. A few years ago, I had swapped in a 90 ECU. I decided to re-install the original 87 ECU. I did this last weekend. Since then, the REM is showing that it switches to closed loop, the ST fuel trim goes up and down, and the Rich/Lean reading is now switching. So, to make a short story long, it looks like the ECU was/is bad.

Last night I picked up a new radiator. May be a few weeks before I can make the switch

I don't remember seeing a club membership question.

Yep. There is a rubber liner that wears out over time. The outer ring will start to drift apart from the inner ring. It will eventually cut the belt and/or the timing cover. You need to change the harmonic balancer.

The pickup needs to trim the rear fenders to fit the tires.

Wahoo, That is why I have not bought from Amazon. I don't like dealing with returns/refunds. My local NAPA has one in stock (NR2802) for $120+tax. Advance Auto can get it (Carquest 432335) for $113+tax. It's funny how the pictures of each one are EXACTLY the same.

Thanks Cruiser. I was looking at that radiator. I was also looking at: this one https://www.amazon.com/dp/B07CSQZ78X/?coliid=I3AYJVTE1SCNLV&colid=3QJUU79LEEST7&psc=1&ref_=lv_ov_lig_dp_it or this one https://www.amazon.com/dp/B000C7S062/?coliid=I275C4Z7OZB8R7&colid=3QJUU79LEEST7&psc=1

I've been watching with interest. I thought it was time I joined in. My e-fan does not turn on when the temp rises above 215F. It only gets hot when idling or stop-n-go driving. Highway driving it runs ~200F I know the fan works. When I turn on AC, the fan runs. I have tested the wiring for the fan. With KOEO, I jump the relay - 30 to 87 - and the fan turns on. I know the relay is good, because the AC kicks on the fan. I unplug the coolant temp switch and jump the harness side wires and the fans turns on. So, all the wiring from the coolant temp fan switch back works as the factory intended. I am guessing that the switch is bad. However, it is "relatively" new. I replaced it less than two years ago because the old one wasn't turning on the fan (parts cannon). Both radiator hoses were replaced at the same time. I am considering changing the radiator. It's approx 20 years old. (Still running closed system. Possible switch to open system.)

I am in.

Congrats! My wife and I are on house #2 and dog #6. Kid #1 just hit 19 yesterday.

The factory light has a weighted switch (mercury?) that closes when the hood is opened. The light turns on. When the hood closes, the switch opens = light off. You will have find a similar type light, or include a manual on/off switch.

Comes up next to the reservoir bottle- Renix. Runs into a wire harness near the relays.

I have the original window sticker I display. Other than that, just me and the MJ.

That's only a 28-Comanche flag.

Thx, Cruiser. My MR277 manual does not have that IS.

Was there a TSB for this? I have the service manuals.
