Sometimes… You CAN “Fix Stupid”...
For all of us Would-Be Diagnosticians (ME included...) who use Cell Phones – Blue Tooth APPs that have these same Torque-Like Diagnostic features… THIS is a Great Instructional Video that Solves Two Distinct Problems. And for @TJBaker57 's "TAPPT" (Torque APP Tweaking) Efforts and for other folks who might also be interested in what Eric “O” from South Main Auto Channel works on from time to time, check out what he does with solving the second problem shown below:
(1) Diagnosing a Non-Classic "No Start" Condition after the Owner Installed the WRONG PCM.
(2) Diagnosing a BAD CAT using STFT & LTFT, the readings of the Upstream and Downstream O2 Sensors along with simultaneous Elevated Engine RPM viewed on the Oscilloscope-like Graphing to confirm this Clogged CAT condition.
Please… ignore the fact that the Subject Vehicle is a Buick Le Sabre… It’s the Basic Principles involved for GM Vehicles that count here:
