I have a 93 2.3 prelude with 107K miles. It has been surging like crazy around 2000-3000 rpms and also stalling at idle if the revs aren't held. Now the tach, bounces all over the place with no effect on the engine except the occasional surge. It will even go down to 0 rpms while I'm driving followed by some surging. I have tried running it with the throttle position sensor unplugged but it still does the same sh*t.

Any input would be cool. Thanks
