Nozzles are calcified. Put some vinegar in the fluid reservoir or just replace/clean the nozzles.

Same as GM. Parts store?

Another huge issue for the sensors to work properly is the ground strap from the firewall to the head stud. Make sure it's there, and if it is, remove the bolt from the firewall and scrape the paint from under the strap. Clean the strap and bolt and reattach.

Felpro one-piece oil pan gasket.

Cool beans.

Bypassing it may give driveability problems. A new/used manifold shouldn't ne hard to find. I have a brand new one.

Tach signal comes from the ICU underneath the coil. Check the connection.

RENIX TPS ADJUSTMENT Before attempting to adjust your TPS be sure the throttle body has been recently cleaned. It's especially important that the edges of the throttle butterfly are free of any carbon build-up. IMPORTANT NOTE: With the Key OFF, and 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 parallels the valve cover and also over near the MAP sensor on the firewall. If you see more than 1 ohm of resistance, or fluctuation in your ohms reading, some modifications to the sensor ground harness will be necessary. The harness repair must be performed before proceeding. I can provide an instruction sheet for that if needed. MANUAL TRANSMISSION: RENIX manual transmission equipped XJs have only a flat three-wire TPS mounted on the throttle body and it provides data input to the ECU. It has three wires in the connector and they're clearly embossed with the letters A, B, and C. Wire "A" is positive. Wire "B" is ground. Key ON, measure voltage from "A" positive to "B" ground by back-probing the connectors. Note the voltage reading--this is your REFERENCE voltage. Key ON, back-probe the connector at wires "B" and "C". Measure the voltage. This is your OUTPUT voltage. Your OUTPUT voltage needs to be seventeen percent of your REFERENCE voltage. For example: 4.82 volts X .17=.82 volts. Loosen both T-20 Torx screws attaching the TPS to the throttle body and rotate the TPS until you have achieved your desired output voltage. Tighten the screws carefully while watching to see that your output voltage remains where it is supposed to be. If you can't achieve the correct output voltage, replace the TPS and start over. Sometimes, after adjusting your TPS the way outlined above, you may experience a high idle upon starting. If that happens, shut the engine off and reconnect your probes to B and C. Start the engine and while watching your meter, turn the TPS clockwise until the idle drops to normal and then rotate it back counterclockwise to your desired output voltage. AUTOMATIC TRANSMISSION: RENIX automatic transmission equipped XJs have a TPS with two connectors. There is a flat three-wire connector, same as the manual transmission vehicles have, and it is tested the same as the manual transmission equipped vehicles, as outlined above—FOR ALL ENGINE MANAGEMENT RELATED ISSUES. However, the automatic TPS also has a square four-wire connector, clearly embossed with the letters A,B,C, and D. It only uses three wires and provides information to the Transmission Control Module. THIS SQUARE FOUR WIRE CONNECTOR IS USED FOR TRANSMISSION/SHIFTING RELATED ISSUES ONLY. Key ON, measure voltage between "A" positive and "D" ground. Note the voltage. This is your REFERENCE voltage. Back-probe the connector at wires "B" and "D". Measure the voltage. This is your OUTPUT voltage. Your OUTPUT voltage needs to be eighty-three percent of your REFERENCE voltage. For example 4.8 volts X .83=3.98 volts. Adjust the TPS until you have achieved this percentage. If you can't, replace the TPS and start over. So, if you have an automatic equipped XJ your TPS has two sides--one side feeds the ECU, and the other side feeds the TCU. FOR AUTOMATIC TRANSMISSION RELATED ISSUES: Check the square four-wire connector side of the TPS. If you have ENGINE ISSUES check the flat three-wire connector side of the TPS. For those with a MANUAL TRANSMISSION--the TPS for the manual transmission XJs is stupid expensive. You can substitute the automatic transmission TPS which is reasonably priced. Revised 09-22-2012 First off, you need to adjust the TPS to get it to idle properly.

And, loosen/remove them first!! If not, the bind on them will make the job much more difficult. I thought E12? Too cold to go out to the garage and check this morning.

The TPS is not adjusted correctly then.

Refresh/add some grounds and your blower will spin faster.

Either do the GM 3.4 swap or get another Jeep.

4 quarts? That's alot of oil. What brand of oil filter did you use and when's the last time you checked the level?

A guy just gave me that set in the box for nothing today. Woohoo!!.

Correct. Tuneup hardware must be in good shape. Plugs, wires, cap, and rotor every 30,000 miles. I like NGK plugs and Napa premium cap, rotor, and wireset. Make sure all your intake manifold bolts are snug. Spray the intake area wit TB cleaner to check for any vacuum leaks. Ever replace the oxygen sensor? Recommended interval for that is about 80,000 miles. The CCV lines need to be free from cracks, obstructions, and accumulated carbon deposits. Those can also cause some oil consumption and wacky vacuum readings.

I'm not sure. Attaches to the kneebar near where the round black diagonal dash brace is. Not far from the velcro for the wiper module IIRC.

Worth a try. Remove your IAT and clean it carefully with a toothbrush and carb cleaner. I wonder if someone,at some time, messed with the throttle body butterfly stop screw.

Think about this regarding puctuation and see how things could be misinterpreted. Yesterday, I helped my Uncle Jack, off a horse. Now imagine that sentence without punctuation. Somebody could get the wrong idea about you, huh?

Do a build thread. I wanna see this.

All tires the same size? Try shifting it like this, but of course from 4 to 2 instead. 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".

And the winner of the award for longest sentence ever is:

How are your motor and trans mounts? Is your exhaust pipe rattling on the crossmeember?

Renix Vacuum Harnesses The vacuum harness that attaches to the front of the valve cover and includes the grommet/fitting, and is called the front harness, is Napa part number BK 715-1367 http://www.napaonline.com/Catalog/CatalogItemDetail.aspx?R=BK_7151367_0269070623 The vacuum harness that is closest to the air cleaner, EGR etc, and is called the rear harness, is Napa part number BK-715-1366. http://www.napaonline.com/Catalog/CatalogItemDetail.aspx?R=BK_7151366_0269070622 The tube from the rear of the valve cover to the intake manifold is part number 715-1365. http://www.napaonline.com/Catalog/CatalogItemDetail.aspx?R=BK_7151365_0066877355 Revised 09-11-2012

Wix, Napa Gold, or Mopar for the oil filter. Fram isn't the only POS filter out there. NGK plugs, Belden wires, premium cap and rotor from Napa. One stop has it all.
