Hi peeps it's me again with another problem on my 94 accord lx(auto). I've been having a few latley since I went over 250K. My problem concerns a rattling/tapping noise coming from the engine, but only when I hit the gas. It seems to go away when I reach a stable cruising speed. I checked my cat because a friend told me that they tend to rattle after a while but it's solid and tight. This noise only happens when I hit the gas.

Also my ABS fluid box looks as if it was attack by acid I'll try to get a pic of it and post it for all to see.

Please help if you can. It just might save me a load of cash.
