St the crossover to LP (low-pass), and around 80Hz for 12" subs or 120Hz for 10" subs. Turn the gain all the way DOWN. Turn the radio about 3/4 or 4/5 the way up. Adjust gain until subs start to sound a wee bit sloppy and then adjust back 1/8 of a turn. Also, DON'T turn the LOUD function on or the BASS all the way up on the radio.... these should really be flat as possible.

Changed out the knock sensor and engine light is still on


Some engine lights don't turn off until the car is driven for awhile. Give it some time. If it doesn't go away, take it to Auto zone to clear the engine code. If it comes back, then it might be a wire problem and not the knock sensor itself. Good luck!

2004 3.0L Escape. Where are the knock sensors located?


Knock Sensor

Print
Operation

The Knock Sensor (KS) is a tuned accelerometer on the engine which converts engine vibration to an electrical signal. The PCM uses this signal to determine the presence of engine knock and to retard spark timing.
Removal & Installation

  1. Raise and safely support the vehicle.
  2. Remove the intake manifold.
  3. Remove the bolt and the Knock Sensor (KS).
  4. To install, reverse the removal procedure and tighten mounting bolt to 15ft. lbs. (20 Nm).

Stalls in gear no getup when pushing the gas replaced 2 knock sensors iac map oxygen 2 coolent sensors ecm spark plugs wires and whole distributer fuel filter valcum hoses now i dont know how to set timing...


Even you knew, before you started changing any parts,
that you didn't need to replace 10 things.

You just admitted to not knowing how to set timing or find
a problem,I knew that when I got the the second part you
installed

You need to study vehicle systems etc & go to a repair
shop for now,that you also knew before you started throwing
parts & money at it.

You realize you provided no vehicle at all,year,make,model

My tune up utility says my prefetch folder is gone and it is important for my laptop to increase the start up..how will i solve this problem?..i didnt delete anythin in my laptop so i was wondering how...


1. Make sure that the task scheduler is enabled. If you are un-sure, go to Start/Control Panel/Administrative Tools/ Click on Services/ Then in the list of services make sure the Task Scheduler is enabled & restart the service by clicking on Start. Close the Services Folder & go back to desktop.

2. Then go to START/RUN/ and TYPE IN cmd (without the quotes) CLICK OK. This will bring up the DOS Command screen.

3. You will need to copy and paste this entry in at the flashing cursor
 rundll32.exe advapi32.dll,ProcessIdleTasks (without quotes) and press ENTER.

4. Now reboot three times and your Prefetch folder will be rebuilt. (It takes 3 reboots for the prefetch folder to work out what it needs)

Hvac blower motor not working after bringing car in for service, was working fine before mechanic did tune up, replaced starter and coil on 1993 gran am withQ4 engine


What is your question? It sounds like you have an old car that will need some repairs. What he did has nothing to do with the blower motor. Turn the switch on, and tap the motor. If it works, you need a new motor. If not, check fuses, switch and blower resistor.

Excessive knocking at at speeds


Please check your oil.
It may be time for a tune up, because your timing
may be off, and that would make it run rough at all
speeds.Look at your spark plugs and make sure
they are not fouled. If they are wet with oil you can get "non foulers" basically a spark plug extention
sleeve. It brings the plug back out a few inches
from the cylnder and the oil can't reach it.
