Bad injector code? 200 1990

posted by  someone claiming to be Ian Martin on  Wed Aug 2 08:31 CST 2000 [RELATED]

I have a 1990 240 wagon with an LH 2.4 fuel injection system.

The other day I started my car (warm start) and the engine hesitated and shook badly. I gunned the throttle and the idle smoothed out but I still experienced a loss of power as I started out in first from the next few stops. Then the check engine light came on. I got a 2 3 1 code (compenstating for a too rich / too lean mixture) and a 1 1 3 code (faulty injector(s)). The injectors check out electrically and when I pulled them, they had no carbon deposits on them.

I also ran through a tank of gas with that fuel injector cleaner, but I still get the same code.

When I reset the ECU memory and then start the car, I immediately get the check engine light and the same two codes.

The car runs great, and my gas mileage is normal.

Is it possible that my O2 sensor is going bad? I know there's a code for this (a code I'm not getting) but the injectors seem to be okay. I've also checked the vacuum lines for leaks but I can't find any.

Can anyone offer any insight? Thank you.
