"What does a new computer cost?"

Big bucks! Rebuilts are probably available from Beckman in N. Carolina.

The bulletin is interesting as it has different recommendations for cars in the Jacksonville zone. It does refer to DM code 19 specifically, but in the zones outside Jax it says to verify long term fuel trim with scanner (lower than .92). It also says to test for other reasons first before replacing the controller. The text of the bullentin is talking about cars in warrantee and the reasons for long term fuel trim adaption at limit increase due to other causes as the vehicle ages.

Email me if your would like the bulletin.
