I might have to buy a spare 951t injector and just swap it out to see if anything improves.
It does smell very rich at idle and my fuel economy sux. It's either a badly set Octane Quality switch on my Motronics, or a badly set AFM, or a leaking injector
These other symptoms would be consistent with a bad injector or a bad fuel pressure regulator (keeping too much pressure in the lines) rather than a poor tune - I assumed that the burping was the only issue.....
