Bogging and sputtering

[allbottledup]

Today i was driving home from work. Hit a light with a black vr6. Had a good two car lengths on it when i hit time to shift in 3rd. After that the car started to bog out bad and stutter when ever i gave it throttle. I just changed and cleaned out my throttle body, IAC. Just put in a new cap and rotor and plugs...the only thing i did last night to the car was get gas....maybe a bad tank?? Let me know if you had this problem before. Also when it warms up it idles between 1500-1700 rpms? Tryed to adjust the idle and it doesnt help.

perhaps some bad gas? i dunno... maybe an injector is sticking open. run any fuel system/injector cleaner lately? probably wouldn't hurt.

alright ill try that...another thing one of my friends said was it might be a bad map sensor...would that cause it to stutter?
