So another tech has a Toyota Echo in the shop with a lean condition. Tested all kinds of stuff, replaced intake gaskets, swapped parts from a known good car, still lean. I'm suspicious of clogged injectors, but no one has an injector pulse tester, and drop testing is not a bidirectional function on this Y/M/M. How can we do this test?
Why, borrow another vehicle that can drop test, of course! Another tech drives an '01 Silverado, comes with an injector drop test as standard. We get the Silverado and the Echo facing each other, run my super long test leads from a disconnected injector harness on the Silverado, and connect them to the corresponding pins on one of the Echo injectors.
Have one tech running the injector test on the Silverado, another on the Echo running the fuel pump between drops, and me moving the test leads around. It works! Of course, the injector drops were identical, so it was all a waste anyway. Figures.
Anyway, I always laugh at the stuff techs will do in the shop that is SO far from recommended procedure. Are we dedicated, or just stupid? Feel free to share your own experiences, I'd love to hear them.
