new but strange problem

[dj_joker_2002]

I installed the rebuilt stock injectors and the van runs better then ever
BUT anytime I drive above 60 MPH I get a code 44 and that's the only time I get it. Anyone have any ideas?

Did you disconnect the battery to clear the ECM so it could "re-learn" its settings after installing the new injectors?

If not, it may be running on some old data resulting from the bad injectors, i.e. overcompensating towards the lean side through the entire rpm / speed range which is tripping the O2 sensor at high rpm.

Yes I disconected it prior to starting the swap.

The ECM may be relearning the system. The problem may resolve itself.
Unless your O2 sensor has coincidentally gone of the fritz, that pretty much taps my ideas.

bump for DJ...
any improvement?
anyone else have any ideas?

I would double check all the connections he had to remove to change out the injectors to make sure they are fully seated. Sometimes old corroded connections can cause problems after they are disturbed. What does the 44 code mean and would it relate to anything you disconnected?

code 44 is "Oxygen Sensor Circuit, Lean exhaust Indicated".
