Coach,
Although I agree with you, as to the so strange comment...I remember years ago a TR coming into my shop with all sorts of running, driveability and backfiring issues. This car had too been recently serviced by a reputable shop. We went down the same road, thus far...as you have. Initially we felt that there was a major fuel injection problem with the car, based on the way it ran, even though the car had very low mileage. The short story, after spending considerable time with this car, with heavily qualified ASE Master Techs...was that "someone" had turned/messed with every single adjustment posssible, in a feeble attempt to "adjust the idle" speed.
I'm not saying that there's not an FI problem. What I am saying...and that I suspect JRV is thinking...is that "all" of the baseline settings must be checked and verified before going any further. Although somewhat of a PIA, it's very reassuring to know precisely what your baseline actually is, before possibly condeming expensive FI components. Simple things first, as I have learned working with these cars...
Your on the right path...and I'm confident that you'll/we'll get you car sorted out.
Regards,
David
