I have been having a similar situation with my 94 Accord EX F22B1 Automatic with 174,000 miles. I noticed for example if I am accelerating at lower rpms that I hear a weird clunking sound. I can feel it slightly in the gas pedal sometimes. I notice it a lot when I am not going that fast like for example in a parking lot or turning corners. I also noticed it if I am driving at higher speeds and I let off the gas and the rpms go down then when I press the gas I hear the clunking sound then its gone once I get up to higher rpms. The sound is not there at normal acceleration. My engine is nice and queit at idle and also when I am driving on the freeway

So I am curious what this might be? Back in January I had the timing belt job done and I am not sure if I remember hearing it before I got the job done. I was wondering if it might have anything to do with the timing or balance shaft system? I know its not the CV Joints. The sound I hear is more of a "clunking sound" It's kinda weird. I know its not rod knock either. I've heard that before and rod knock is always there. The sound I hear is not always there. I also noticed when I put the car in neutral and rev the engine the clunking sound starts at about 1,500rpms and then goes away at about 2,000 rpms. The sound comes from the timing belt side of the engine. I am thinking it may be something with the timing belt. Ive had my valves adjusted and my engine is quieter but the sound is still there. Have you listened under the hood to find where the sound is coming from? Any help is appreciated, Thanks.
