Question about 2004 Ford F150

1 Answer

Hi ! I have a 2005 F150 with a 5.4L engine and if

Hi ! I have a 2005 F150 with a 5.4L engine and if you apply full throttle the engine cuts out severly. If you don't go to the floor with the pedal and stay just off of 100% the engine will rev right up to 5000 rpm with out a single miss or any problem what so ever. So I have ruled out it to be a fuel delivery problem or ignition problem. But i am wondering if that would be a tps or throttle positioner. Anyone run into similiar problem before. Cool thanks for you time !!

Why won't the car start with the new Crank shaft position sensor installed? 2005 Buick Lacrosse cxl 3.8l engine.


After replacing crank sensor Perform the crankshaft position system variation learn procedure. Refer to Crankshaft Position System Variation Learn !
No you don't need to replace the balancer !
Install a scan tool.
Monitor the powertrain control module (PCM) for DTCs with a scan tool. If other DTCs are set, except DTC P0315, refer to Diagnostic Trouble Code (DTC) List - Vehicle in Vehicle DTC Information for the applicable DTC.
Select the crankshaft position variation learn procedure with a scan tool.
The scan tool instructs you to perform the following:
4.1. Accelerate to wide open throttle (WOT).
4.2. Release the throttle when fuel cut-off occurs.
4.3. Observe the fuel cut-off specifications for the applicable engine.
4.4. The engine should not accelerate beyond the calibrated RPM value.
4.5. Release the throttle immediately if the value is exceeded.
4.6. Block the drive wheels.
4.7. Set the parking brake.
4.8. DO NOT apply the brake pedal.
4.9. Cycle the ignition from OFF to ON.
4.10. Apply and hold the brake pedal.
4.11. Start and idle the engine.
4.12. Turn the A/C OFF.
4.13. The vehicle must remain in Park or Neutral.
4.14. The scan tool monitors certain component signals to determine if all the conditions are met to continue with the procedure. The scan tool only displays the condition that inhibits the procedure. The scan tool monitors the following components:
• Crankshaft position (CKP) sensors activity--If there is a CKP sensor condition, refer to the applicable DTC.
• Camshaft position (CMP) signal activity--If there is a CMP signal condition, refer to the applicable DTC.
• Engine coolant temperature (ECT)--If the engine coolant temperature is not warm enough, idle the engine until the engine coolant temperature reaches the correct temperature.
Enable the crankshaft position system variation learn procedure with the scan tool and perform the following:
Important: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete.
5.1. Accelerate to WOT.
5.2. Release when fuel cut-off occurs.
5.3. Test in progress.
The scan tool displays Learn Status: Learned this ignition. If the scan tool indicates that DTC P0315 ran and passed, the CKP variation learn procedure is complete. If the scan tool indicates DTC P0315 failed or did not run, refer to DTC P0315. If any other DTCs set, refer to Diagnostic Trouble Code (DTC) List - Vehicle in Vehicle DTC Information for the applicable DTC.
Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.
The CKP system variation learn procedure is also required when the following service procedures have been performed, regardless of whether DTC P0315 is set.

How to adjust governer to increase speed on 2002 Jacobsen 1110 hauler?


If this is a diesel engine then adjusting governor to get more speed will destruct the engine. If the vehicle is slow then when the engine is off have someone apply full throttle and see if you can still move the accelerator lever on the pump. If you can either adjust the lever to full throttle stop position or get a new accelerator cable.

Engine keeps cuting out when breaks are applied


I would say idle air control valve sticking. its common on Renaults. This valve controls the air passing through the throttle body when you open and shut throttle. eg, foot down throttle open, the idle valve will be shut. back off throttle, then the air is shut off through main throttle body, so the valve opens to allow just enough air in for tickover. if valve sticking or moving to slowly it will not open in time to catch the idle when throttle shut, hence it cuts out.
