Knock or rattle

[Riddler]

I have a 1995 525IT with 105.000 miles. I have a knock or a rattle if you want to call it that. It only happens when the car is going up a steep hill or when I am accelerating. I will not do it if I but the brake on and give the car gas. I only use 93 Octane in this car.

maybe the knock sensors arent working, do you get any codes with the stomp test?

Well I don't know what a stomp test is but I am not getting any error codes.

Well I pushed the button under the tack for three seconds then turned the key to position 2 and the car went through some numbers then came to code and it said 0000. So I'm taking that as no codes. Is this the same as the stomp test?

No, Riddler, that's not the same test. The codes you see holding the Code Check Button, and turning the ignition to posn 2 reviews the various electronics codes on the car and tests the instrument panel. The stomp test (as noted by 632 Regal above) will indicate if there are any system failure codes held in the car's computer. I believe if if you have no stored codes, you should get a 1444 (blink - pause - (x3) blink, blink, blink, blink - pause).

Getting the stomp to work is all in the rhythm and is going to take practice...it may even be frustrating.

I got mine to work once I found the right level of frustration and coordination. If, for example, you press down on the accelerator for an "F", and let up on a "U", then the following should work well: "F-U", "F-U", "F-U", "F-U", "F-U", "you little piece of @#@$#*&*@#$&...work, dammit!" The pause before an F and U should be about the same time as when you say "uh-oh", as in when your wife finds out you have just bought another expensive upgrade part for your E34 without mentioning it (getting approval) earlier. =:-o

Cheers,
Duey

Well I tried this twice and flooded my car. That is what pissed me off. Do I just leave the key off and then turn it to what position?

Thanks for your help.
