Thanks for all of the advice.
To answer the first question, when coasting down hills or driving with no throttle input, it is fine. The only time it acts like it wants to stall is immediately after starting. It gets fairly rough and I was hoping that it running rough like that immediately after starting would not cause other problems. It kind of shakes the car and sounds bad when it is almost stalling.
My coolant guage inside of the car seems to be pretty accurate. It always starts out at the bottom of the gauge, and then when running goes up to around 200 degrees F. Is the temperature sensor the feeds information to the PCM the same as the one that feeds information to my guage? If I were to replace the temperature sensor, where would I find it? Also, in the last most reply about unplugging the MAF, is that something that is easy/cheap to replace?
Thanks again for the help
