suddenly no throttle response while driving?!?!

[spidy3]

I was driving down the road in 4th gear at 3k rpms accelerating a little. all of a sudden it was like 2 little sputters then my car stopped accelerating. I put it to WOT and nothing. took my foot off the gas and stomped on it again, no response again. kept trying it then car sputtered a little (almost like fuel cut) then finally started to drive normal. when i got on the highway it did the same thing in diff gears @ diff rpms. My current thoughts on this is my TPS is going bad. any other thoughts or options i would be glad to hear. I will be getting pocketlogger monday and will hook it up and have it showing TPS and maybe CAS to see if signal drops off. This is second time my car did this but the first time was like 1-2 months ago. Please let me know any ideas. Also when this happened my knock gauge did not move if that helps any. and my tack just stayed at the rpms it was at.


Thanks,

Dom


*note - current mods should be in my prof.

Make sure the battery is tied down and an insulator on the positive. Otherwise they move when accelerating and short against the hood (killing all ignition, etc).

Check your speedo cable. Make sure it's not too loose.

think i figured out my problem. My GM MAF sensor had stuff on it (paint chips from IC piping and some other minor things. I cleaned it off at work sat. and hasnt done it since.
thanks for responses tho
