I'm building the tool that turns the tech's cryptic note into a calm, customer-ready explanation — the kind you can read out loud and watch them relax. Get early access.
P0301 cyl 1 misfire, coil DOA, plugs gapped wide.
RR brakes metal-to-metal, rotors scored past spec.
Sway bar end link play.
Cust: shudder @ idle + grinding on stop.
You mentioned a shudder at idle and a grinding noise when you brake.
A failed ignition coil is keeping one cylinder from firing cleanly — that's the shudder. Your rear brakes are worn down to the metal and have scored the rotors — that's the grinding.
Replace the coil and spark plugs for a smooth idle, and replace the rear brake pads and resurface the rotors so you stop safely and quietly.
Built to read brake jobs, no-starts, overheats, A/C and the rest the same calm way — and built to never invent a price, a part number, or a warranty. Just your tech's diagnosis, in plain English you can copy straight into the estimate.
Drop in the tech's scrawl and the codes, exactly as they were written — nothing to clean up first.
It returns the same diagnosis as a calm Concern / Cause / Correction your customer can follow.
The kind of explanation a nervous customer relaxes hearing — so an honest job stops sounding like a scam.
I'm building this for independent shops. Leave your email and I'll let you in the moment the first version is ready to use.
