Prompt Cards

Create an electrical diagnostic plan using voltage drop testing. Include battery health, grounds, connectors, relays, fuses, load testing, intermittent faults, and documentation of measured values.

Create a fuel trim analysis workflow: STFT/LTFT by idle/load, vacuum leak indicators, MAF/MAP errors, injector issues, fuel pressure, exhaust leaks, and sensor plausibility checks.

Interpret OBD-II data like a technician: freeze frame, fuel trims, misfire counters, oxygen sensor behavior, MAF/MAP plausibility, and readiness monitors. Provide a diagnostic worksheet.

Create an engine misfire diagnostic tree: ignition, fuel, compression, vacuum leaks, sensors, wiring, ECU data, and mechanical timing. Include test order and evidence required before replacing parts.

Help diagnose automotive driveline symptoms: clunk, whine, vibration, shudder, backlash, or load-dependent noise. Include differential, CV joints, U-joints, mounts, transmission, and tires in the hypothesis tree.

Create a drivetrain wear assessment for motorcycles and bicycles: chain stretch, sprocket/chainring wear, cassette condition, belt tension, alignment, lubrication, and replacement strategy.

Create a diagnostic flow for wheel bearings and hubs. Include noise by load direction, free play, heat, roughness, seal condition, installation errors, and post-service validation.

Teach me to interpret tire wear patterns: cupping, feathering, shoulder wear, center wear, flat spots, heat cycles, and sidewall damage. Map each pattern to likely causes and next checks.

Create a tire strategy for cars, motorcycles, or bicycles based on surface, load, weather, speed, and ride goals. Include pressure tuning, wear reading, heat signs, casing choice, and replacement criteria.

Diagnose steering or handling complaints: vague steering, head shake, tramlining, understeer/oversteer, wobble, or poor turn-in. Include checks for tires, alignment, bearings, suspension, frame/fork condition, and load distribution.

Create a suspension setup workflow for cars, motorcycles, and bicycles. Include sag, preload, compression/rebound damping, ride height, geometry effects, tire pressure interaction, and a test loop for tuning.

Create a troubleshooting guide for bleeding hydraulic brakes or clutches. Include air sources, master/slave cylinder behavior, hose routing, reverse bleeding, vacuum bleeding, and signs of internal seal failure.
