Default knocking and pinging on MY00 rs

Well, I think my car is starting to knock and ping. Bought the car new in 2000, and just recently I noticed it. What's the best solution you guys have?

there are alot of things to consider
what kind of mods do you have
what kind of conditions do the knocking and pinging happen at
what kind of gas do you put
how long has it been doing this
do you have a cel

I notice that my MY00 pings quite a bit when the weather is hot and I'm crusin up a slight incline. It's definetly related to the weather - since the weather has cooled off here in Vancouver, the pinging is almost nonexistent.

LaterZ!

The brand of gas and octane rating of it will have an affect on the motor. I always stick to Amoco and their 92 octane. Get the good stuff for your motor.

(I have the ProECM chip installed. The gas price is expensive, but the throttle response and acceleration makes up for it).

The gas I've been using is the costco stuff, 91. Don't laugh. Their gas is actually not bad at all. And plus, they go through so much of it that it's always fresh, and they change out the pump filters more often. Besides, I always see MB, BMW, and Audis there (all new models).

In terms of mods, just an intake and exhaust, grounding mod, (the rest is just handling stuff). I thought the weather might have somthing to do with it, but it hasn't been all that hot lately.

There was no load on the car except me. 1/4 throttle. Sometime it shows up under full throttle. Wierd.
Well, come next week I plan on tearing everything apart, as my new struts are coming in, and fluids, and plugs. Speaking of which, last time I used Redline all around, but I forgot the quantities we need for front tranny and rear lsd. Doh!

If you haven't changed the plugs, do so. While you are at it, I'd grab a set of wires too.

Well, the plugs went in, along with a new fuel filter, a bottle of injection cleaner. Hopefully that works. I wonder if the fuel injectors themselves are shot??

If the plugs dont help try new wires. Mine was doing a similar thing and when I replaced plugs and wires it made all the difference in the world.

bringing this back from the dead... why would the plug wires make a difference with knocking/pinging?

and would changing to a colder spark plug make any difference?

i'm currently running 89 octane in an 03 forester xs ej25AT trying to get rid of the noise... hoping not to have to go to premium because gas is expensive in my parts

If your plug wires are decomposing, they'll deliver less energy to the spark plugs, which will therefore produce a weaker spark. New plug wires = more spark energy = better combustion. This may or may not help pinging.

if it goes with the idle of the car it might be your throw out bearing?

''no automatic's do not have a throw out bearing, instead of a clutch/flywheel they have a torque converter(fluid coupling), now the torque converter does has torrington/roller bearings inside of it." -drummerRS2505

Modern cars with knock sensors should not be knocking and pinging. If it is, that tells me something else is wrong.

Because many have experienced pinging problems caused by bad spark plug wires. One cylinder (maybe more) would misfire, causing the ECU to detect a rich condition, and lean out the mixture to the other cylinders, causing the engine to ping. Look for open wires, intermittent wires, and leaking wires.

The knock sensor can only retard ignition timing to a certain limit. Even without knock sensors, a car should not ping. If the knock sensor has to pull out timing, then yes, there is a problem.
