Integra acceleration problem

On several occasions my Integra has lost all power for brief periods of time. Under acceleration, it just "falls on it's face". I engaged the clutch it and rev'd it up, and it rev'd fine, and then idled fine. No check engine light, and no codes are in the ECU. It has happened several times, but never consistantly. I'm thinking it is the TPS. The Snap-On scanner that was hooked up showed at an idle my throttle was at 9.4%, and when floored it showed the throttle was at 89.1% (the engine was off and the key was on during the scan). I've heard that the dealership sells TPS's only with the throttle body. Anyone had this same situation? Please help if you can. I appreciate it!! I may look into an aftermarket throttle body with new TPS. Thanks!!

What year and model car?

Sorry, it's a 1996 Integra LS

if it is a very high mileage car, it is possible that the exhaust has crap in it. Happened to my benz. Just check air/fuel/spark. Make sure the air flow is perfect from intake to exhaust, you are getting spark at all rpms, and u getting fuel. Mayebe a bad/going bad pump?
