|I didn't know what I needed for my little car (a 1988 325 Convertible) in anticipation of a 2000+ mile road trip but they took care of everything.
I started my road trip with a much-improved car and I had a nice journey.
I arrived safely and without incident (except for a speeding ticket -- maybe it ran too well)!

Since the TPS, when working well, switches the fuel injection between idle more and non-idle mode, it seems logical to assume that the former was not being activated, and the latter cannot do a good enough job of keeping the idle steady -- wwhich is why there IS a separate mode for idling. On the E30, that separate mode uses a different set of components, such as the idle control valve vs. the mass air flow sensror (a.k.a. air flow meter).
The problem vanished when he replaced his suspect part with a good used part from us.
