I recently have a clicking noise that is somewhat random on my '04
Coupe. The noise only appears after about 1/2 hour of driving on the
highway at ~70 MPH. The car typically experiences this when I am in
6th gear. It is not really linked to acceleration as the clicking
noise is just random. It does happen more frequently when I accelerate
though. It almost sounds like spark knock but I use 93 octane always.
Chevrolet cannot ever get the problem to occur as they never have the
time to drive it. The noise sounds like it is coming from the engine.
I have no reduced power. It is just annoying on a $45K car. Any help
Park it in a dark garage with the hood up. Start it and watch the spark plug
wires. Your computer can be adjusting for a leaking wire or cracked plug
porcelain so it's not noticeable in performance but it can be seen in the
Warning, exhaust fumes can kill you so don't do it very long and/or in an
air tight garage.
Maybe you should just tell him to do it at night with the lights off and the
garage door open.
I know, I know. Lawnmowers have warnings on them not to put your hands
under the deck when running and hair dryers have warnings not to use them in
the shower or bathtub. Duh!
Don't rub it in, I admit to being guilty of some of those "DUH!" type
moments. Besides, what's wrong with using a hair drier in the shower, just
don't plug it in, most showers don't have plugs anyway. Knot the wash cloth
in the cord and it makes a good crevice cleaner. ;-)
