Nissan Pathfinder

2000 Nissan Pathfinder V6 … New battery installed 1 week ago … Starts right up no problem …. Here’s what’s going on …. You’re driving along and everything is fine. Then suddenly the engine seems to slightly shake and then suddenly stalls! The ONLY strange thing (could be related or not) is that in very cold weather without a sufficient warmup, reverse is fine but once it’s in drive there seems to be a clunking noise which you can feel. Then it drives and runs okay!!! At a loss now, any idea’s?


Slightly shake and then suddenly stalls

First place to start would be pulling any check engine light codes.  May or may not show a code. If it does, post code back here in the comments. Most common cause for this issue would be the crankshaft and or camshaft position sensor failing.

For your transmission issue, check the fluid level. If it is full but dark and burnt looking instead of pinkish red, there may be internal damage. Check the color on a white paper towel. Having the transmission fluid and FILTER changed may correct this issue.

Lexus RX300

No power and seemed to have cut off

A few weeks ago my 1999 Lexus RX300 started running rough and using more gas than usual. The check engine light had been on since I bought it in
September but there had been no issues before this. Took it to Advance Auto and had the computer scan done, Cylinder 1 and 6 misfires. Replaced
all coils and spark plugs, reset the light. Ran good for about 3 days then it was hard to start and keep running, figured it was cold natured and began
warming it up for 15 minutes or more before driving. A couple more days later the check engine light flashed a few times, car acted like it had died (no
power and seemed to have cut off), then the car was shaking and acted like it had been shifted down suddenly (transmission revving and RPms racing).
My dad ran a scan on it, but no codes or anything show up. The check engine light only comes on during these episodes, which last only a few
seconds, and seem to happen more when it’s cold (the weather or the car) and when I take my foot off the gas pedal to slow down. What could be
causing this?


My initial guess without looking at it would be the Intake Air Hose is loose. Check for loose hose clamps from the engine air cleaner/filter assembly that connects to the MAF Sensor. Or a loose hose at or around the MAF Sensor. Probably got knocked loose or accidentally left loose when it was worked on.

Only clicks when try to start. Rotate engine by hand and it goes a quarter turn and stops in either direction. Any idea what could cause that?


First Remove all spark plugs before trying to rotate the engine by hand. This engine has a timing chain. So if you have recently been working on it, the timing may be off and the piston is hitting the valves. Under normal circumstances this will not occur. If the engine was making a lot of rattling before it stopped running, it is possible that there is an issue with the timing chain guide(2 & 4) or timing chain itself has broken.

Mazda B4000

I just bought a mazda b4000 and the guy told me that I had to put in neutral to put on 4×4 and then put it in reverse when the light comes on but I’ve put it on drive to turn the 4×4 button (yeah I’m dumb😅) now the light blinks 6 times and then stops for 2-3 minutes even if the button is on 2 high and I cannot hear the transfer case motor… I have need help… it’s tough in Canadian winters on 2wd


4×4 light blinks 6 times every two minutes

4×4 Blinking Lights Possible Cause
  • Wiring
  • 4×4 shift motor
  • 4×4 fuse – Be sure to check FUSE#13 in the battery junction box under the hood.
  • GEM – Generic Electronic Module
ACTION:

Perform On Board Diagnostics with scan tool to retrieve DTCs (Diagnostic Trouble Codes)

  • Connect Scan Tool
  • Select Diagnostic Data Link
  • Next Select GEM – Generic Electronic Module
  • Finally Select RETRIEVE DTCs

Flashing lights usually means its stuck between 2 wheel high and 4 wheel high.

You can pull the shift motor and turn the **** with pliers.  Otherwise cleaning it or replacing it are your options.

For my 84 f-150 351cleveland big block with a 4 barrel edlebrock carb with raised edlebrock manifold and heads. can’t find this part anywhere. It is a pigtail that converts a 3 wire distributor to a 4wire electric Ignition module. 3 prong female end to a 4 prong male end on the module. no-one can figure out what I’m talking about or find the part.


Distributor wiring harness pigtail

I get what you are looking for. Here is an example of what I think you want. However, I did not find the part listed at Jegs or Summit Racing. You may just have to make your own wiring harness.

In 1984 Ford used the Duraspark II system. This refers to the Duraspark II control module with a BLUE strain relief bushing, one 4-pin connector, and one 2-pin connector. Another version of the system has an additional 3-pin wiring connector, and two YELLOW strain relief bushing’s. Source: Handyman Dan

Automatic transmission won’t go into gear from full stop when cold. If I manually shift it isn’t an issue. Not original owner. Don’t know it’s history before I owned it.


My opinion without looking at it would be an internal issue if the fluid level is full and looks clean. If the fluid looks dirty or dark, a rebuild is in your future.

Some sound opinions found on the net:

Transmission will not shift when cold

sounds to me like when it’s cold the fluid is thicker of course and is not pumping thru as it should. Might want to at least clean the filter, maybe it’s clogged up and won’t let fluid thru until it gets warmed up or something? Source: Swims350

Transmission will not go in gear when cold

This is a classic symptom of internal hydraulic leakage inside the transmission. As a transmission gets older, the various seals inside of it that keep fluid confined in specific channels tend to become hardened and no longer pliable enough to seal tightly against the shafts, servos, and other components that they are attached to. Often, in warmer weather they may seal enough to allow the transmission to operate somewhat normally. But when colder weather comes this tends to cause them to shrink more and become less pliable because of the lower temperature. After the engine runs while and the transmission fluid warms up, the internal seals and O-rings expand slightly and become slightly more able to do their job.

Repairs Needed

The repair needed is a transmission rebuild: removing the transmission from the vehicle, disassembling it completely, and installing all new seals, O-rings, and gaskets. Of course this is pretty expensive because of the amount of labor involved….

As a temporary measure, what often helps is to take the vehicle in to a shop to have the transmission flushed; this involves using a machine to push all of the old worn out transmission fluid out and replace it with new fluid. Transmission fluid contains additives that help to keep seals soft and pliable, so replacing the old worn fluid often helps somewhat. Also, adding one of the various transmission stop-leak or seal conditioner products available at any auto parts store to the fluid sometimes is beneficial. These products work by softening rubber components and causing them to swell up slightly; this improves sealing ability, especially when cold. Keep in mind though that this is not a fix; it only buys some time until transmission overhaul is needed. Source: Auto Mechanic: Steve

Rear bumper. What all is involved in removing the rear bumper??? I have a standard bumper but will be putting a step bumper on it. Is there a different mounting bracket for the Step Bumper or is everything the same???


Everything should be the same. Remove four nuts, install the replacement bumper and tighten the nuts.

Rear Bumper Removal

  1. Remove the 4 retaining nuts from the rear bumper.
  2. Remove the rear bumper.

To install, reverse the removal procedure.

◦To install, tighten to 70 Nm (52 lb-ft).

2005 Chrysler Pacifica

ABS light keeps coming on and then off


ABS Light On

Generally speaking this has to do with the wheel speed sensors going out. They are mounted inside the wheel hub bearings.

“The 05 and 06 models have a lot of issues with the wheel speed sensors for the abs system. A failing sensor will cause the symptoms that you are describing.
Because of excessively high failure rates, Chrysler has re-designed the sensors and for this reason it is necessary to replace all 4 sensors…………even if just one is bad.” Source: Chrysler Mechanic

Anti-Lock Brake System, Inspection

A visual inspection must always be performed to confirm the presence of aftermarket components, potential collision damage, or areas of concern.

The ABS module is self monitoring. The module will carry out a preliminary electrical inspection of the hydraulic pump motor by turning the pump ON for approximately 1/2 second either when the ignition switch is turned to the RUN position and the brake pedal is not pressed or when the vehicle is in motion and at vehicle speeds above 12 mph. The ABS module will also carry out a wheel speed sensor self-test by sending a reference voltage to all of the wheel speed sensors through their circuitry when the ignition switch is turned to the RUN position, with or without brake pedal application. If a fault is detected in the pump or wheel speed sensors, the ABS module will shut down and disable the anti-lock system. Normal power assisted braking, however, remains.

  1. Verify stop lamps operate correctly by applying and releasing brake pedal with ignition switch in OFF position.
  2. Verify that PRNDL operates correctly on instrument cluster.
  3. Visually inspect for obvious signs of mechanical or electrical damage.
  4. If an obvious cause for an observed or reported concern is found, correct cause if possible before proceeding.
  5. Connect a suitably programmed scan tool to vehicle DLC.
  6. Carry out network test.
  7. Clear continuous DTCs and carry out self-test diagnostics for ABS
