It just started knocking out of no where. Only when press fuel not in idle

Occurs everytime.

This is the 2nd Tracker I've owned and both had the same squeak. Its more noticeable on bumpy roads. I thought it may be the steering wheel column, but I greased that and still hear it. I thought maybe its a common problem since its happened on both my cars. I can fix it if I know where its coming from. Middle console/dashboard area?

It doesn't do this every time. It's just does it out of the blue for no reason that we can find.

But once in gear runs fine. Do I need to take in for repair?

Help. I am out of ideas. The pulsing did not start until I changed the pads. No ABS.I also change the rear brake shoes when I first change the pads. Thinking rear brakes may nor be adjusted. I bought the necessary "caliper tool" ad adjusted the rear brake accordingly.

Front brakes are still pulisng afte new rotors and new pads. I am out of ideas.

code 721, replaced mass airflow detector, 6 weeks later same code. Can this be caused by a bad gas cap? What other solutions ?

runs great up to 60 then struggles to come up to speed,could this be a weak fuel pump or regulator or maybe bad fuel injectors?was pulling a p0113 code,so I replaced the MAP sensor and the service engine light did go out,but still not coming up to speed.THANK YOU

Will a starter and ignition switch fit from a 2.01L 2003 tracker to my 2004 tracker 2.6L?

From a 2003 2.01L fit mine?
