Loud "clunk" at low RPM?

While driving at a low RPM, either at 20MPH or 50MPH, I will get a "clunk" noise when I gradually accelerate. Only one clunk.

When at high rpm I will not get the noise. Everything is smooth.

I fear it may be the torque converter. Hopefully not. But I am stumped.

Any suggestions?

Could it be the center support bearing in the drive-shaft (if your body style has a center support bearing)?

Actually, I need to check the U-joints. I don't know why I didn't think of it before. Hopefully it is that.

I changed the driver's side u-joint and wheel bearing.

However, now injector #5 is misfiring. I think I got bad fuel the other day. It makes the truck shake. Anyhow, how do I fix this? I changed my nozzles before so I am familair with injector removal -- but how do I clean it or fix the problem?
