I have a 98 Civic LX 5 speed. A couple of years ago, the "Check engine" light went on and the car would stall out at intersections. My regular mechanic was out of town and I went to another garage who replaced the front O2 sensor (aftermarket). After that, I became aware that the car would start to feel as though it was losing power ( at about 55 mph) for a few seconds, and then surge forward. My mechanic thought that it was a fuel issue. He then replaced the injectors (i ordered them online - aftermarket). The injectors ended up staying up in the very rich range most of the time. I ordered another set that are better, although still perhaps abit in the high range (the reading is apparently in the 70's but does drop down immediately upon decelaration). He also replaced the catalytic converter and both O2 sensors (all aftermarket) based upon codes and info that was coming up on the scanner.

The check engine light still comes on and the code shows it running rich. The freeze frame at the time the light comes on shows a very low rpm rating (160) which is why he thinks that the "rich" code is showing. He has checked the distributor, wiring and sensors, and is now is wondering about the computer. It shows abit of moisture damage on the outside but looks fine inside.

Any thoughts or insights would be appreciated.
