It starts great but after a few minutes of running cold,warm, hot, any time you start up after a few minutes of running it runs very rough. If you driving it acts like it is running out of gas, I hammer the gas it down shifts and takes off, no more issue after till you stop. if you let it warm up sitting it runs rough, and it is very loud hissing noise like its sucking as if chock is open or something for a minute then the idle goes up comes down and it fine and the hissing is gone. I replaced Idle Air Control motor nothing, then I did a tune up and it helped but it still does it, could it be the TPS or MAP. no check engine light.
