2500rpm bog!!

When my car is at 2500 rpms it bogs really bad then goes away. It only does this at 2500rpms and partial throttle only. It has a great idle and runs smooth other than this extreme bog. It lasts for a split second but enough to make the nose dive and lift back up. Everyone has told me that it is the throttle position sensor, but I wanted some 280z experience answers.

Thanks- James

Hmm, probably need some more detail. Try going to atlanticz.ca and getting the EFI bible to do some diagnostics. I will tell you that the 280Z doesn't have a normal throttle position sensor with varying voltage. It has an open/close circuit to indicate at very low or closed throttle and another open/close circuit to indicate >~60% throttle (WOT). If you get it to bog at a very specific throttle range ONLY at 2500 rpm then it could be that it's not kicking into the WOT switch or out of the closed switch fast enough and going somewhat lean, etc. It could be a lot of other things, though, since you didn't indicate that you had actually tried anything before posting.
