1985 Ford F150

Truck loses power intermittently

My truck, a 1985 Ford F150 5.8 liter V8 4-barrel Carb,  has dual fuel tanks not sure that is necessary for this problem. I have changed the fuel pump fuel filters, had the fuel pickups rebuilt in the tanks and had the carburetor rebuilt. The problem is that when driving in high temps (above 90 degrees) the truck loses power intermittently, similar to running out of gas, typically starts on an incline and problem does not always appear. Any advise on what is going on would be helpful.

Sounds like the float level needs to be adjusted in the carburetor. The fact that it doesn’t seem to happen until you start on an incline is what leads me to this thought. The other thought would be vapor lock when the temp is over 90. Leave you fuel cap off once and test.

Carburetor Troubleshooting

The best way to diagnose a bad carburetor is to eliminate all other possible sources of the problem. If the carburetor is suspected to be the problem, first perform all of the adjustments.. If this doesn’t correct the difficulty, then check the following. Check the ignition system to make sure that the spark plugs, breaker points, and condenser are in good condition and adjusted to the proper specifications. Examine the emission control equipment to make sure that all the vacuum lines are connected and none are blocked or clogged. Check the ignition timing adjusting. Check all the vacuum lines on the engine for loose connections, splits or breaks. Torque the carburetor and intake manifold attaching bolts to the proper specifications. If, after performing all of these checks and adjustments, the problem is still not solved, then you can safely assume that the carburetor is the source of the problem.

The float adjustment is a preliminary fuel level adjustment only. The final adjustment (Wet) must be performed after the carburetor has been installed on the engine.

With the fuel bowls and the float assemblies removed, hold the fuel bowls upside down and turn the adjusting nuts until the floats are parallel with the top of the fuel bowls.

NOTE: The fuel pump pressure and volume must be to specifications prior to performing the following adjustments.

  1. Operate the engine to normalize engine temperatures and place the vehicle on a flat surface.
  2. Remove the air cleaner, and run the engine at 1,000 rpm for about 30 seconds to stabilize the fuel level.
  3. Stop the engine and remove the sight plug on the side of the primary carburetor bowl.
  4. Check the fuel level. It should be at the bottom of the sight plug hole. If fuel spills out when the sight plug is removed, lower the fuel level. If the fuel level is below the sight glass hole, raise the fuel level.
    Do not loosen the lock screw or nut, or attempt to adjust the fuel level with the sight glass plug removed or the engine running as fuel may spray out creating a fire hazard.
  5. Adjust the front level as necessary by loosening the lock screw, and turning the adjusting nut clockwise to lower fuel level, or counterclockwise to raise fuel level. A 1 ⁄ 16 turn of the adjusting nut will change fuel level approximately 1 ⁄ 32 &inch; (0.8mm). Tighten the locking screw and install the sight plug, using the old gasket. Start the engine and run for about 30 seconds at 1,000 rpm to stabilize the fuel level.
  6. Stop the engine, remove the sight plug and check the fuel level. Repeat step 5 until the fuel level is at the bottom of the sight plug hole, install the sight plug using a new adjusting plug gasket.
  7. Repeat steps 3 through 6 for the secondary fuel bowl.
    NOTE: The secondary throttle must be used to stabilize the fuel level in the secondary fuel bowl.
  8. Install the air cleaner.

2001 Ford F150Outer bearing races will not come out. I’ve used two different types of slide hammer pullers. All that is left are the outer races. I started making some conservative “x” cuts with a dremmel on the race , but I am concerned about going any deeper at risk of cutting into axle housing. What else can I do. Need some advice!

Removing Rear axle races

In my shop what we used to do in order to get races out was to use heat. I have found that the best way to apply heat to the race is to use a wire welder. Weld a bead all the way around the inside of the race and it will pop right out.

2003 Ford Focus

My car wont crank. The lights and radio come on and makes a rapid clicking noise when trying to start.


Rapid Clicking Noise When Trying to Start

Your Battery is weak. The battery is not strong enough to turn the starter over but has plenty of power for the lights and radio. The radio requires as little as 5 amps to function. The starter requires as much as 250 amps. Charging or replacing the battery will be required. If the battery is close to 4 years old or older, replace it anyway. It will save you from a repeat situation.

2011 Ford FiestaWhat are labor hours to replace transmission connector Part #AE8Z-7G276-A.

I have located the part and it appears to be a wiring harness. I do not show the hours in the labor guide. Generally electrical work is performed by the hour. However I can provide you with this. It only takes 6 hours to remove and reinstall the entire transmission. So the hours had best be well below that.

2006 Ford F150A day after I had the 4wheel drive actuator on the passenger side replaced. I was driving along and the front end started shaking like a tire was about to come off. By the time I pulled over it was just a steady vibration. Now when I hit any kind a bump I can feel it in the steering wheel and the pedals. I’ve put all new tires and alignment, both front wheel bearings, brakes and rotors and sway bar links on with no change. I took it to our local Ford garage where they told me everything in the front end is tight and in good working order. Please help

This is one that is just going to have to be looked at. You may want to take it to a different shop and get a new look with fresh eyes.

2004 Ford Cargo VanVan starts shuddering when I Accelerate , has low power. Idles fine. Shudders until it shifts into passing gear, runs smooth until it drops into driving gear and then starts shuddering again. What could the problem be?

Generally has to do with the torque converter and or other internal parts sticking. Not using the manufacturers recommended transmission fluid may also cause this situation. If this started just after a transmission fluid change they may have used the wrong fluid.

What I would do first would be to have the transmission fluid flushed and filter changed. Then I would add in some “Shudder Fixx”. All you have to do is add it to the existing transmission fluid. Yes, I have done this before with great success.

2006 Ford TaurusCheck charging system light came on while driving. Is it safe to drive?

When the check charging light comes on it indicates the battery is no longer being charged. This means the entire vehicle is now running on the battery until the battery dies. And it won’t take long to drain the battery. So is it safe to drive, not really. Could you drive it a couple miles up the road? possibly without issue but no guarantees can be made.

Ford Crown Victoria

I’m getting code p0351

I’m getting code p0351 from my 2007 Ford Crown Victoria Police Interceptor  and I’m wondering what it means and what I need to do to fix. My car drives really ruff and horrible on gas since this code appeared. Please help registration is due in June probably will not pass smog.

Ford Code P0351

Ignition Coil ‘A’ Primary/Secondary Circuit

Each ignition circuit is continuously monitored by the Engine Control Module (ECM). The test fails when the ECM does not receive a valid pulse signal from the ignition coil.

Ford Code P0351 Description

The ignition system on the vehicle uses individual ignition coils for each cylinder. The Engine Control Module (ECM) controls each ignition coil operation. The ECM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.

Ford Code P0351 Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Lack/Loss of Power
  • Engine may be harder to start
  • Engine hesitation
  • Rough engine idle
