I too am having the surging RPM issue but have not recently changed coolent and additionally hear a relay ticking/switching noise near the fuel filter corner of the engine compartment --have you determined the root cause & fix??? VB4tqbooo@Yahoo.com
The knock sensor is exactly what it says. It senses any knock or ticking in the engine and retards the timing. The knock sensor is not the problem, the knocking is. Go to a repair shop and have it diagnosed.
Normally loose tappets will cause a ticking sound in the engine. Depending on if you have mechanical or hydraulic tappets you may need to have them replaced or simply adjusted.
only way to stop lifters from ticking is to replace the lifter. ticking or noise from lifters is caused by parts being worn most times whenthis happens the nlobe on the cam that the worn lifter is on, is also worn,so you have to decide if it is worth paying for both to be replaced
The ticking could possibly be from a timing key going out. Having mine replaced presently.
the ticking noise is likely the fuel injectors, which you probably didn't notice before because you weren't looking for anything wrong.
Check the fusebox, it will be a big looking fuse. This will need to be replaced if the turn signal stops "ticking"
a lot of 3.1 engines do this, if it is not severe then it should be ok...
No. The word ticking is a verb form, or a noun, or an adjective (ticking clock). But it is not used as an adverb.
Typically no. You may have a loud pump....usually indicating it will need to be replaced soon.
the ticking is the blinkers
Time Is Ticking Out was created in 2001.
If the ticking sounds like a "normal" ticking, it is probably the fuel injectors.
