2006 Ford TaurusI have a 2006 Ford Taurus with P0300 Ford random misfire. changed: manifold gasket, fuel filter, spark plugs, wires and coil pack. the misfire is off and on and at idle.


P0300 FORD – Random Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

The P0300 code means that a cylinder(s) is misfiring or is randomly misfiring. Start by checking for intake leaks, intake gaskets are common caused of multi-cylinder misfiring. If no leak are found the next step is to replace the spark plugs. If the problem persist more tests needs to be done to diagnose problem, see “Possible Causes” below.

Possible causes

– Faulty spark plug (s)
– Faulty ignition coil (s)
– Clogged or faulty fuel injector (s)
– Intake air leak
– Fuel injectors harness is open or shorted
– Fuel Injectors circuit poor electrical connection
– Ignition coils harness is open or shorted
– Ignition coils circuit poor electrical connection
– Insufficient cylinders compression
– Incorrect fuel pressure

– Sticking or faulty fuel injector
Possible symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
– Lack/loss of power
– Hard start
– Engine hesitation

head gasket 2005 Ford TaurusHow much would a mechanic charge to replace head gaskets on this car?


Much would depend on the engine as it may be DOHC (Double Over Head Cam) or not.

Around $1600 this includes gaskets, coolant, oil, cleaner, misc and labor.

The gasket set is under $100 plus mechanic mark up on parts = $150 – $200

Looking for help troubleshooting problems
No acceleration on hills actually truck will slow when throttle is pressed. If gas petal is feathered truck will maintain speed eventually will slow down
Recently bought truck has new fuel pump, filter, catalytic convertor and O2 sensor. seem like the last owner was chasing some issue?
Truck will run great 70 mi. then act up is key is turned off truck will run fine for 4-5 mi then die. Leave it set and it will run great again


Your in luck as it is a 1995 Model. This means you can pull the Computer codes without a scan tool.

Post any codes found below in the comments for further help. If no codes are present than I would be looking at fuel pressure drop on acceleration. A drop in fuel pressure may be from the a leak or a failing fuel pressure regulator. At idle fuel pressure should be around 30 psi and should increase to 35-45 on acceleration.

If the problem seems to happen more when the engine is hot versus cold, I would lean more toward the ignition control module as it is the most common failure component in the ignition system for this year. And there will be no code for this.

1997 Ford ExpeditionWhen I bought this truck last week, it had a kill button installed on the dash. Today when I pushed the button twice nothing happened. I checked the fuses, and tried again. It started but kept grinding and trying to start, so I turned it off. Now it wont start again. What should I look for?


Not sure why it would need a kill button? If you are having trouble with the starting system use the wiring diagram below to check your system. You may need to remove this aftermarket item and put it back the way it is supposed to be. If I had to guess. the starter motor relay or the starter itself is causing an issue.

When the ignition switch is turned to the START position, the starter motor solenoid relay switch is energized connecting the battery to the starter solenoid. The starter solenoid moves the drive lever and pin (11067) to engage the starter drive with the flywheel ring gear and connects the battery to the starter motor.

2006 Ford FocusCan a serpentine belt burn up because of alternator may be bad ac compressor lock up or burn up on my 2006 Ford Focus?


Yes. If the compressor or alternator is locked up the belt will great a large amount of friction as it slides over the pulley and burn the belt.

Belt Tensioner

Automatic tensioners are calibrated to provide the correct amount of tension to the belt for a given accessory drive system. Unless a spring or damping band within the tensioner assembly breaks or some other mechanical part of the tensioner fails, there is no need to check the tensioner for correct tension.

2008 Ford TaurusSometimes acts as though it does not want to move after coming to a stop and trying to turn left.


Possibly a sticking brake caliper. Without touching the wheels, see if one is particularly hot. This would be an indication to look for. Touching the wheel may cause you to get burned. Be careful. You may also want to put the vehicle on jack stands. Turn the steering wheel and see if anything is rubbing or causing the wheel from spinning freely.

Brake Caliper Removal

 WARNING: Do not use any fluid other than clean brake fluid meeting manufacturer’s specification. Additionally, do not use brake fluid that has been previously drained. Following these instructions will help prevent system contamination, brake component damage and the risk of serious personal injury.

 WARNING: Carefully read cautionary information on product label. For EMERGENCY MEDICAL INFORMATION seek medical advice. In the USA or Canada on Ford/Motorcraft products call: 1-800-959-3673. For additional information, consult the product Material Safety Data Sheet (MSDS) if available. Failure to follow these instructions may result in serious personal injury.

 CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water.

 CAUTION: Do not allow the brake fluid to come in contact with the adhesive backing on the brake pads. This may prevent the brake pad adhesive surface from bonding with the brake caliper. If brake fluid is spilled onto the brake pads new pads must be installed.

 CAUTION: Use only specified brake parts cleaner. Use of other cleaners may leave a residue on the brake caliper preventing the brake pads adhesive surface from bonding with the brake caliper.

  1. Remove the brake pads. For additional information, refer to Brake Pads.
  1. Disconnect the parking brake cable from the subframe bracket and the caliper.
    • Position the parking brake cable aside.
  1. Clean and inspect the disc brake caliper.
    • If leaks or damaged boots are found, install a new disc brake caliper.
  1. Disconnect the brake tube fitting from the brake flexible hose.
    • To install, tighten to 17 Nm (13 lb-ft).
  1. NOTE: The brake caliper and brake flexible hose are removed as an assembly.Remove the retainer clip from the brake flexible hose.
  1. To install, reverse the removal procedure.
    • Bleed the caliper.

2001 Ford F150I have access to a 2004 v6 engine. Will that fit into a 2001 ford f150 that i need a new engine for.?


Yes. The 4.2L engine (Long Block) will fit your 2001 Ford F-150. You may need to change over some of the components and wiring harness if you are going to try and use all the sensors, etc. If you stick with just the long block you shouldn’t have any issues.

2004 Ford ExpeditionHelp please. I replaced #4 ignition coil and while moving hoses I may have unplugged a connector. I have two unplugged passenger side connectors.  One is a 2 wire the other 3 wire. The 2 wire is red wr and blue wire next is 3 wire I believe it is grey blk red maybe pink. Both are located behind pcm coming out of silver thing bolted to firewall. Truck wont start but starter good, battery good but no power to ignition side of starter. All relays good turn key relay clicks help please.


  1. Check for battery negative at starter case
  2. Check for battery positive at the “S” terminal on the starter while someone holds the ignition key in the “START” position
  • If Battery positive is found, replace the starter.
  • If no battery positive is found, trace the wiring harness back and repair as needed (see wiring diagram)

2004 Ford ExpeditionI have an ’04 Expedition. Started fine all morning. Let it sit about an hour or so, went out to go to work, turned the key, everything comes on but it won’t even turn over. Starter or solenoid aren’t making a sound. There is a buzzing type alarm coming from what sounds like the passenger floorboard, which I’ve never heard before.


Most likely a weak or dead battery. If the lights on the dash go dim or completely out when you hit the key it would indicate the ignition switch is working. The radio and lights do not require much amperage to operate. This may give you a false sense that the battery must be good, but it probably isn’t. Once you have fully charged and load tested the battery or replaced it, it still has the same issue a test may be necessary. Check for battery voltage at the “S” terminal on the starter while someone holds the ignition key in the “START” position. If you see battery voltage, replace the starter. If you do not see battery voltage, trace and repair/replace as needed.
