Intermittent rough idle on a 5.0L F-150 with a cycling MIL is consistent with a VCT system fault or carbon buildup on intake valves. Recommend pulling freeze frame data and checking for P0011/P0021 before disassembly.
How it works
A service writer creates or updates a repair order in Tekmetric. CoreDiag picks it up automatically — no tab switching, no duplicate entry.
CoreDiag reads the vehicle, concern, history, and NHTSA data. A structured diagnostic suggestion is generated in seconds.
The suggestion is posted back to Tekmetric as a note on the RO. The tech sees it the moment they pull up the ticket — and can rate its accuracy when the job is done.
"My techs started asking for it on every ticket."
