My brothers' stock 97 Integra is stumbling when you gun it or at least mash the gas pedal, its not sensing the load. It doesn't act up when you take off slow and give it gradual gas. There is no check engine light either which I hate, I swapped out the map sensor and still does it. I just learned that there is no EGR valve. TPS maybe? Has anyone seem this problem before? Thanks in advance.

 

havent heard about this type of problem but bump for an answer and good luck. im thinking its something simple maybe a tune up or o2 sensor
