Hi Frank,

When you clear the codes from the OBD box you are not resetting the memory that holds the compensation (trim) the ECU made for any conditions you've since fixed.

One of those large fuses is for the fuel injection and engine management. I can't be specific about which one or how they are marked, but the idea is to pull the fuse momentarily to completely clear the codes and the adapting trim. You'll know you've done the job when the OBD returns to 111 and you did not do it with the push button. Lifting the battery terminal does just as well, but I'm trying to save your radio presets by sending you the fuse route.

It may not fix anything, but should remove all doubt your ECU is holding a radical trim adjustment in memory. And it is so easy.

Being right is highly overrated. Even a stopped clock is right twice a day.
