Partially clogged injectors and code 2-3-2 ? (b234) 700 1990

Dave,
I had another thought,I installed the O2 sensor tonight and I disconnected the battery ground so the system will start fresh with a new strategy; and I am checking the block sensor for cold resitance in the morning.When the engine is hot(200F) the value is around 190-210 ohms on either terminal to engine ground,which is close to specification.I also thought about the check valve in the fuel pump,the one on my 89' turbo was bad,although the turbo displayed delayed starting problems due to the fact that the LH 2.2 doesn't pressure up the fuel rail untill the starter is cranked,unlike the LH 2.4 on the b234 engine which will pressure up when the key is first turned to the ignition position,I wonder if a defective check valve might affect the the constant fuel pressure at idle and cause a idle mixture problem?
I will be reporting back,
Scott
