Default Acceleration Problem. A sensor?

I have a problem that I wonder if anyone else has encountered.

At times my 2004 standard begins to buck wildly if the RPMs reach between 1300 & 1500. In fact, I can't increase the RPMs beyond that point. If I keep the RPM below that, no problems. Speed isn't the issue. If I do it slowly, I can eventually come up to cruising speeds, though hills do slow things down.

I have noticed a few other things about this.
  • Often, if I turn the engine off, and restart it, that solves the problem.
  • Restarting the engine back into its normal state is easier if the temperature gauge reads below normal (the middle mark).
[LIST][*]If I have the cruise control on, this turns it off, and I am unable to re-engage it.[/LIST
  • It seem more prevalent in hot, and/or damp weather.

A short time back I had to replace most of my cooling system. At that time the check engine light came on, and was diagnosed as a cooling issue. The car's temperature issues have been solved. About the only thing I didn't replace was the sensor.

Is it possible this is being caused by a bad temperature sensor?

The problem isn't bad, yet. However, it's becoming more frequent, and I'd like to address it before it become critical.

Any Ideas?

Do you work on your own cars?

Have you looked into the suggestions below?

If you are not getting any engine trouble codes check the wires and plugs next to the PCM. With the engine running wiggle all the plugs and see if it causes the problem.

Is your upper and lower strut mounts bad allowing the motor to go back and fourth? This might allow some harness wires to stretch and rub on the engine block shorting possible wires to ground.

Check your fuel pressure. You should be getting 58 +/- 5 PSI

If you don't post what you have done already when we offer suggestions then it will then it will most likely not get solved.
