The oxygen sensor broke off, and it ran fine for a few days, then one morning the car would only start with the pedal pushed most of the way down and shook very bad at idle.
I checked all the mounts, checked the spark in all 4 plugs, replaced the fuel pump fuse and checked fuel pressure, and replaced the oxygen sensor- to no avail.
The ecm is throwing the error code (too much circuit resistance).
I took it to a shop and they basically just started throwing parts at it hoping that it would fix the issue. After a 500 dollar bill I told them to stop and am going to replace the ecm if I don't find out anything, but its a fairly expensive part new and I don't want nothing to change and be out more money.
Is this a common problem (the ecm frying after the oxygen sensor is disconnected) or is there another issue?
