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


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).

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.
