You do NOT need elaborate computer testing rigs and harnesses. A few manual gauges taped to the rear glass while you are driving round is good enough.

It is system knowledge and logging that key right now; and you can easily do that yourself--in fact, I highly recommend it

If you have USD$1200 you can buy an elaborate test harness with computer outputs. This system has to be learned; further compounding your pain. (If it is not painful: you are not learning).

This engine management stuff is not that difficult with stock ECU's. There are not very many inputs/sensors that you have to worry about. But the computer learns and makes non-obvious control decisions.

What has made YOUR car difficult is that we have no idea what baseline you are operating from. Some critical "factory only" adjustments may have been botched, other adjustments were made blindly and I'm also guessing that original problem that started this whole thing still remains.
