Probably shoulda done that about 115 posts or so ago............

Thank you for your post. It really is that easy........

Mr 100 plus posts? Sketchy info? Poor listener? Black cloud?

106 and counting.....................

Too cool!!!!

Screwed into the intake manifold rearward of the throttle body. In the photo above, if you could see THROUGH the intake boot to the deal connected to the connector with 2 black wires, that's it. Do the ground refreshing, connector refreshing and C101 refreshing FIRST.

You can use 2357s in place of 2057s and they're brighter. 795s in place of 1156 in reverse ligts. Also brighter.

Junkyard.

Intake Air Temp sensor. It can be removed and cleaned.

O2 sensor is a real possibility.

Meaning? Don't tell us that you didn't upon buying, or haven't as a normal course of maintenance, checked you drivetrain lubrication fluid levels and condition...... woops long response fluids were good when i got it, i have just found out from experience that on any incline my tcase pours its fluid out through the rear seal and is shot off the driveshaft from centrifugal force if in motion, which i can reproduce :rotfl2: that seal will be replaced next week, now that the seal is known to be shot, they are monitored closely You're off the hook for now then...........

Try resetting your TPS now that the grounds are good. And no, the muffler won't CAUSE a miss.

Shifting like this? Here's how the factory suggests you shift the transfer case and I've been doing this since these things were new and I worked at the dealership. Quoted from the owner's manual. "To engage, shift the transfer case lever from 2H to 4H while the vehicle is moving at any legal speed". I let off the gas, throw the lever, and then tap the gas and let off. 4L position: " To engage, slow the vehicle to 2-3 MPH , shift the transmission to Neutral, then shift the transfer lever to the right and pull firmly rearward to 4L".

100 replies and it's still popping. :doh:

It will be running like a "dream" in the near future. I would do the complete ground and connector refreshing as a matter of course if not already done.

Did you do it? LOL. Fess up if you did.

Should come out of the injector harness near the back of the valve cover, unless it had the factory bypass done.

Cruiser’s Renix Sensor Ground Test This sensor ground circuit affects the CTS, TPS, IAT, MAP, ECU and diagnostic connector grounds. It’s very important and not something to overlook in diagnosing your Renix Jeep as it is common for the harnesses to have poor crimps causing poor grounds. If any or all of the sensors do not have a good ground, the signal the ECU receives from these sensors is inaccurate. Set your meter to measure Ohms. Be sure the key is in the OFF position. Using the positive (red) lead of your ohmmeter, probe the B terminal of the flat 3 wire connector of the TPS . The letters are embossed on the connector itself. Touch the black lead of your meter to the negative battery post. Wiggle the wiring harness where it runs parallel to the valve cover and also near the MAP sensor mounted on the firewall. If you have an 87 or 88 with the C101 connector mounted on the firewall above the brake booster, wiggle it, too. You want to see as close to 0 ohms of resistance as possible. And when wiggling the harnesses/connectors the resistance value should stay low. If there is a variance in the values when wiggling the wires, you have a poor crimp/connection in the wiring harness or a poor ground at the engine dipstick tube stud. On 87 and 88 models, you could have a poor connection at the C101 connector as well. Revised 06/12/2012

TPS won't cause "very rich" running. Clarify please. Did you do the Sensor Ground Test? Wiggle the harness etc? What were the ohms readings? MAP sensor can cause extremely rich running if the tube from the throttle body to the MAP sensor is cracked, melted, loose etc. Same thing can be caused by a poor connecor fit at the MAP.

Be sure to do the sensor ground test!!

Click on the link in my signature and find the TPS instructions. Or, click on this: http://www.cherokeeforum.com/f51/cruiser54s-mostly-renix-tips-153657/

I have a writeup in that link for Sensor Ground Upgrade........

Yep. Leaning that direction myself. but now would be a good time to check the sensor ground circuit as it not only affects the TPS, but the CTS, IAT and MAP. Their signals run through the C101 also.

I only see ground refreshing and TPS adjustment in post #1.

I would start by clickng on the link in my signature and doing the ground refreshing, C101 cleaning, Connector refreshing and Sensor ground testing. The TPS adjustment procedure is in there also, but do the other groundwork first, in the order given. Good luck.
